I need some advice. This year we are having problems with chickens dieing when we move them to the backyard. The first time it happened, it was chickens that I had bought who were about 5 months old. We had them in the front yard for a month to make sure they were healthy. Then when we moved them to a new coop, that was near our old coop (to let everyone get to know each other), and they started dieing. I couldn't pay the $160 to have a necropsy done. Now we moved our "chicks" to the back yard. And the same thing is happening. They are 6 months old and have been here the whole time. We moved their coop from the front yard to the back yard. We did not put them near where the others were. The area that I put them in has never had poultry (well at least the last 11 years, I don't know about before that). Other than free ranging. We have had poultry here for 6 years. We did not get any new birds last year, but we did have a few unexplained deaths during the winter. But they were older hens, so I don't know if it started then. They start to act drowsy, and then die by the next day (usually within a few hours). I don't know what to do. All I can think is maybe a wild bird brought a disease. But then I wouldn't know how to fix the yard. We live in Michigan if that is important.
