I got 8 chicks about 4 weeks old around the middle of March. This was my first time owning chickens and I just thought that I would lose one or even two over the first week, for no reason but I just thought they were fragile. So far they had all made it and I began to relax. I think they were in horrible conditions living at night in a 100 gallon stock tank that by morning had a filthy waterer. They went out in a small run (4 x 12 wire) during the day while hubby was converting a spare horse stall. We finally finished it about a week ago and both the chickens and I were very happy. I went out to check on them about 4 PM and I noticed that one was huddled in the corner sorta like what I think a brooding chicken will look like. I have seen several of them do this at one time or another tho. I looked at the chicken and I couldnt tell anything was really wrong. I went back out about 5:30 PM to feed and find the previously huddled up chicken dead. I have absolutely no idea why and I am now worried about the rest of my chickens. The floor is dirt which is a mixture of sand and clay. And I sprinkled DE on this floor before they went in it. I was kinda worried about it being on the floor that I thought they were going to be pecking on but as I read on this forum it should not have hurt them. I guess time will tell in the following days whether the rest will be ok.
