I had 5 baby turkeys, one got sick with what I thought was an injured leg. Turned out to be contagious apparently. Progressive Symptoms in order are: loss of balance, falling over backwards, weakness in legs, lethargy or inability to stand and then seizures. It seems to take about 2 weeks to come down with it. I separated my baby chickens from the baby turkeys when I realized the turkey was sick. All 5 turkeys ended up dying. This chicken has been separated for about 3-4 weeks now and this week has started falling over. I'm really concerned because I put them in the pen with my big girls 2 weeks ago. So far this is the only one showing symptoms. I added these babies to the pen and kept them fenced off from the big girls for a week- removed the fencing and had them altogether for 2 days and then reposted the fencing because my Wyandotte was keeping them in the corner so much I was afraid they were going to starve. I've had them separated by fencing for another week and they have grown a lot. I want to remove the fencing again, but now with this one sick I'm afraid for my big girls. I have no idea what this is and have not talked to anyone who understands what it could possibly be. Everyone down plays it but 5 turkeys are dead and now a chicken is sick. Please help! One more thing- this chicken could possibly have been sick about a week longer than I realized because I did notice that it kept strangely stretching its wings a lot. I've never seen any others do that.
