Hello, I have lose three of my chickens in the last four months. I have no idea why.they have a great coop very nice run I feed them good food and always have clean water,plus veggies and scratch. I was letting them free range part of the day when I could watch them but No longer I don't think there is anything they could have eaten but couldn't be sure. It does get pretty hot here in high 90. I put mister on run. They have been in this coop about 9 months just not sure what to do...Frist chicken that died,just slowed down and stopped eating And the second I notice her comb started losing color and size. Then I came home and found that # 3 was walking using one foot and By the end on day was just sitting not wanting to move. WTH I love my chickens and have worked hard to make sure they are safe And happy. Could there be problem with dirt ?? I did call vet not much help there. Really at a loss Out of the eleven only have 9 left About three months ago my husband build me a new coop and I got 15 new baby chicks They are find but I am nerves!!!
