I am new to raising chicks and got a mixture of 12 chicks from Atwoods. Yesterday one of my black ones started laying around and wouldn't eat or drink. He died a couple hrs later. Now one of my red ones is doing the same thing. I gave him some sugar water by syringe and seperated from group he was kind of chilly when I picked up so I have him on a heating pad. ( it's 90 in the brooder box and all other chicks are running around playing). How can I save this poor baby???
