Hello all, While I have read information on this site periodically, I have just created an account. If anyone can steer me in a direction where I can figure out what's going on my with hens, that would be great. We've had chickens for about 4 years now, with about 20 hens and one fabulous rooster. In the last month or so we've lost 4 hens to natural causes (2 were showing strange signs, 2 seemed pretty much completely normal the day before they up and died), and one was so bad off (very bloated, waddling like a penguin when she absolutely had to move. She was still eating but she couldn't lay down because she was so bloated and not feeling well.) that we had to cull her. We have two more (one more than the other day) who are acting funny. Nearly all of the hens that have died had been kicked off the roost. The most recent one that has shown strange symptoms is just now sleeping off the roost and on the floor. I have just today changed their straw/bedding. We've used straw over hay the last couple months.... any ideas or areas for me to research?
