We recently went and got some little baby chicks and one of them has a weird eye. His eye over a period of time "grows" a substance. He is the sweetest little thing ,but he acts weird too. He falls asleep on his feet! The other chicks take the time to lay down, but the poor little fellow seems weak. The other chicks struggle when I pick them up or put them on their back, but he just lays there and does nothing.(Unless one of the other chicks comes and picks on him, in that case he gets up.) Please help!!!
