Duramycin 10 and eggs

Tuesday, December 13th, 2011


Ever since we received a question about the use of Duramycin 10 to treat chickens we have received a steady stream of visits and questions related to Duramycin 10 despite the answer we gave to the original question stating that we have never used Duramycin 10 and knew nothing about its application or associated side-effects. Not that we mind, apparently no one else knows about it either.

Duramycin 10 is an anti-biotic commonly used in the treatment of animals. Because we live and keep our chickens in the UK where such medicines are strictly controlled, we cannot easily get hold of Duramycin 10 without first visiting a vet. It’s hard to justify prohibitably expensive vet bills when chickens are so cheep (excuse the bad pun).

This doesn’t help our international chicken keeping visitors who live in countries with much more friendly chicken keeping laws and who are seeking information about the practical application of anti-biotics to chickens.

After being asked how long eggs remain inedible after treating chickens with Duramycin 10 for the umpteenth time we decided it was time to find out the answer to this great chicken keeping mystery for ourselves.

Now you might think it would be easy to find out about such a commonly used medicine (at least commonly used everywhere except for in the UK where we have such silly medicine control laws), we knew the answer must be out there on the internet somewhere and exhaustedly we searched and searched (well Sandi did since she is the internet guru out of the two of us) but to no avail.

Despite finding the question posed in forums, on the Q&A sections of distributers and retailers of Duramycin 10, and even on the all knowing yet somehow unanswering mystical magical Yahoo Questions, we could not find a definitive answer.

In fact, the closest answer we could find to this great answered question of how long before eggs laid by chickens treated with Duramycin 10 become edible again was a blanket statement that the whole of the Duramycin distribution cartel seem to have agreed on ..

“It is recommended that this not be given to layers”

I think that by the time most chicken keepers think of asking this question, it’s too late!

So we needed to dig deeper! We teamed up with one of our international chicken keeper readers, Rene’e, who shared our deep desire to answer this question about chicken keeping that seems to have eluded the internet community thusfar.

Some research, and some small amount of time banging heads against a wall, we finally tracked down the contact details of a US based company who not only manufactured Duramycin 10, but also was willing to talk to us, or Rene’e specifically. Rene’e, being the kind, sharing, and generally helpful chicken keeper that she is, was good enough to forward the reply she received which read:

“You need to discard the eggs for 3 weeks (21 days) after the last dose of Duramycin 10.”

So there you have it, straight from the horse’s mouth so to speak. With thanks to Google, Rene’e, and Durvet (the manufacturers of Duramycin 10) we hope we have finally put this great unanswered question to rest.

How to prevent recurrence of Chronic Respiratory Disease?

Tuesday, December 13th, 2011

First of all I would like to commend you for what you do for the every day back yard farmer! I have been in the chicken business for around a year and up until about two months ago have had no problems. I introduced new members to my flock and that’s when my problems began. Long story short my entire flock has CRD this problem can’t be fixed, only treated!

I am going to have to cull my entire flock to get rid of the disease. There are commercial poultry houses nearby and I can’t take a chance on the disease spreading! I am going to start over with a new batch this spring.

My pen is fully enclosed but has no top on the run. I have a shed 8 by 10 with three of the sides covered for them to roost and get cover from the elements. I use sawdust about 6 inches deep for flooring. I am going to remove all of this and disenfect the entire pen before introducing my new flock.

My question for you is if this efficient enough or do I need to take more steps! Also how often do I need to clean out the pen and disinfect it to stop this problem from coming back? The entire pen is roughly 400 SQ. feet and cannot be moved around. Any suggestions would be greatly appreciated! Brandy


I’m sorry to hear about your cull, it must be awful having to start over. I’m not a vet but I know a little about CRD.

I did a bit of research on the mycoplasma gallisepticum bacteria that causes CRD and I found a good article that I feel answers your question better than I could! http://www.thepoultrysite.com/articles/222/what-is-biosecurity

It doesn’t seem to me that the bacteria can last long in the outside environment without chicken hosts. That means if you disinfect thoroughly on a regular basis – perhaps once a month if that is practical – and prevent any bacteria from being introduced, you should be ok.

It might be worth limiting the amount of contact you have with other poultry farms whilst establishing your new flock, as CRD is transmisable through clothes and poultry equipment.

I was wondering what would be acceptable to disinfect with? I have heard you could use bleach but wondered if this would hurt the chickens! My new chicks- all fifty of them- should be arriving soon so I need to be ready. I was also wondering if you had heard of the medicine -Duramycin 10- and if I could give it to the chicks as some sort of vaccination while they were young. Any suggestions? Brandy


Unfortunately I am not familiar with that medicine. Because in the UK, controls on antibiotics and other medicines for birds are so tightly controlled, we have to get on without them for the most part, unless we want to include some expensive vet bills.

Part of our strategy to avoid transmittable diseases within our chicken flock is using a fully collapsible chicken enclosure which we can move when we need to. We leave the ground to rest for at least six months before putting any chickens back on it. This should break the life cycle of most poultry diseases and it suits us because we have the luxury of enough space to be able to.

For disinfectant we use Jeyes Fluid for all our animals and it is very effective. A water-bleach solution should be just as effective but like any cleaning product, make sure it has a few hours to air and to dry before you let your birds in.
