Hi. I have a small flock of hatchery silkies that have been sickish from the start. Well, not all of them. Four of them showed/ are showing symptoms of what I believe is Avian Encephamyolitis. Symptoms are neck/head vibrations, drunken walk/ stumbling, and general wobbliness. None have died. They are now 5-6 weeks old and of the four that showed symptoms, all have improved. One still visibly vibrates, one still walks like a drunk, one that had severe walking problems has regained total use of legs, and the other one occasionally does something clumsy. All eat and drink like champs. I will say the vibrating one is much smaller than the others. I also have a crossbeak chick from the same shipment, go figure. My question is, when can I reintroduce these four to the rest of the chicks?
