I just got 4 baby chicks from a friend & they have slowly been dying for no reason. They were eating and running around the first day or so & they have food, water, & clean shavings in their brooder. Then we came home sunday to 1 dead, 1 really lethargic & not hardly moving; while the other 2 were ok. That night she passed away in my hands. Then all of a sudden today 1 of the remaining 2 died after seeming fine. Now I an laying on bed using my body heat & heart beat to keep her warm & peaceful. Anyone know what I should do? She won't eat or drink, she just lays there. Please someone help!
