Hi, I have had 3 chickens die in the last month and a half. They were all between 10 and 14 weeks old, and had not been vaccinated. The strange thing is, there were hardly any symptoms. The first was just found dead one morning, no previous symptoms. The second had an infected eye which we treated with salt water flushes and neosporin, and it died a few days later- this one was lethargic and slept all day for the last few days. The last was lethargic one morning, ate some that day, and then died that afternoon. Any ideas? another maybe important thing is that all these chickens seems a bit small for their size, compared to other chickens their age. We could get this last bird necropsied for $66, and i am tempted because i want to know what's wrong! Thanks.
