hi, i have 5 chicks , 3 of them are perfectly fine. 1 grew alot since its older than the oders. the oder 2 are 3 days old and seem to be fine. 1 died yesterday, it could walk and didnt eat. one chick is smaller than the oders , it looses balance a lot and doesnt realy eat and its sleepy all the time. it looks like it got hicups. it searches for place to rest her head. It is lighter than the others and doesnt really strugle when i pic her up. the first day she was following me the oters also. but now the chick doesnt really follow me anymore. is it okay ?is something wrong with her? please help me!
