Hi All, I am brand new to raising Chickens and I do not know what is going on. We have 2 different flocks. They are separated. We got a flock of 8 as babies from Tractor supply and they are now about 4 months old. We ordered another flock online and they are about 6 months old, just started laying 2 days ago. We have found 2 dead chickens from the tractor supply bunch. Both times, they were fine the night before and dead inthe nesting box in the morning. This morning when I went out one was on the bottom of the coup. Breathing slow and eyes closed, clearly dying. I fed her suagr water by dropper and got her under the heat lamp. I am about to go back out and I sure she will have passed. I am just not sure what the heck is going on??? The picture is when I found her and put her up in the heat section. When I left, she was just laying down not holding her head up.
