I bought 8 babies from www.mypetchicken.com. I got 5 americaunas, 2 blue cochin and 1 silkie. I have since lost all but 3 (2 americaunas and 1 blue cochin). I lost 2 at one time. My husband thought maybe it was from them laying on top of each other and suffocating the ones on the bottom. Then I lost another 1 who was laying off by her self. The last 2 I lost this morning. 1 was laying in the middle of the pen and the other 1 was laying in her food dish. UGH! What am I doing so wrong? I put them outside since they have all their body feathers, wing, tail, etc. They do not have their head feathers though. I do not put the heat lamp on during the day but at night we keep it on until about 8:00 a.m. Our day time highs are 80+ and the nights are between 55 and 75....but I do use the red heat lamp at night still. What am I doing so wrong? They get fresh water every day. They get fresh food as they need it. They are about 1 month old. I also let them run around in the grass every now and again. I noticed today that 1 of the remaining americaunas is now limping. Any help or suggestions would be greatly appreciated. Thanks!
