Hi and thanks in advance for any help you can give. I am not sure what's happening in my flock - wry neck? marecks? Something else? I purchased 18 hatching eggs and added one of my own. I had 13 hatch. 2 of the chicks from the eggs I purchased died in the first 3 days having symptoms similar to wry neck. The chick from my eggs developed the symptoms, but somehow survived. They had tremors ... And their necks started twisting sideways and backwards. The two that died could not eat or drink. They also very rapidly lost use of the legs looking almost paralyzed on one side. It progressed rapidly. I braced myself for the worst, but everyone else survived. About 2 weeks ago The chick from my eggs started with what I thought was rye neck symptoms again, but then I realized he was only turning his head to see. I believe he is blind in one eye but healthy, growing at equal if not faster rate than the others. Now the newest problem. My 2 year old hen that hatched my own egg, is now acting as if she may be going blind as well. She is totally unrelated to all the others. The chick with the eye problem is now 10 weeks old. What is going on? It's been 10 weeks and just now the older hen is developing this problem. I've been searching for any disease/sickness but nothing seems to match quite right. Any guesses or suggestions are appreciated. I've been giving them vitamin supplements about 3-4 times a week. They've been wormed, treated for cocci, and given a 7 day course of duramycin. No improvement in either. All the other chicks and 2 other broody hens are great showing no problems. I have no idea what to try next. There are no avian vets within 2 hours of here ... Possibly further but I gave up and stopped looking as the expense coupled with the travel and time off work to get there is not doable. Any help is greatly appreciated. Could this be mareks? And does that mean that my 38 other birds are immune as they've all shared housing/grass, etc. my chickens range in age from 8 weeks to almost 3 years old. Should I pull out my two with eye trouble? I'm thinking they've all already been exposed. So overwhelmed by all I've read about Mareks. I feel like the worlds worst chicken mommy. Also sorry if I've posted this wrong.
