So I have a mixed flock of what was 13 hens. They are almost a year old. We got them as day old chicks and they were vaccinated with the vaccines offered at Murray McMurray. I have been raising chickens now for almost 6 years. My last flock was only 5 hens, and they all lived for 5-6 years and were all killed by predators. This flock has been up until five days ago healthy and strong with no signs of disease. About two and a half weeks ago my buff Orpington, Sonnet suddenly became what I assumed was broody. We separated her and the day before she died she seemed to be coming out of the broody situation I thought she was in. That day she acted completely normal and was back with the rest of the girls. She did not appear sick or anything. The next day when I opened the coop she was passed just laying on the floor with no injuries. After a little more research I came to the conclusion that what I thought was broody behavior maybe was actually a sign of being egg bound and I then assumed that is probably what killed her. We were terribly heart broken- she was my husbands special bird and she was just such a sweetheart. Five days later, today I opened the coop door and after the rest of the girls ran out, I noticed Ray, my lovey black Astro seeming to have trouble walking. She slid down the ramp instead of walking and I scooped her her up to examine her. Her mouth was open and she just seemed to be in and out of consciousness. I thought her eyes were glossy but it could’ve been because she was dying. At this point she could no longer stand and then she did some flailing and passed away on my arms. Last night she was perfectly fine. She had no signs of any sickness at all. Now I’m devastated. I obviously no longer think that Sonnet died from being egg bound and am starting to think I have some kind of disease or something that is attacking my girls. We are surrounded by woods and have turkeys and rabbits and all kinds of wildlife frequenting our yard But never entering their enclosure. I am just looking for some direction of finding what could be causing this so I don’t have to lose anymore. Any advice would be greatly appreciated. Thank you.
