I just had five chics hatch out. Two of them I put in a brooder by themselves because they seem to have health problems and were getting trampled and pecked on. One chic drags one leg behind him and gets easily excited and looses balance hopping everywhere. It's foot lookes kind of withered and a little odd. This chic seems stressed but eats and drinks fine............ ..... The other chic wont get up at all. It scoots where it needs to go using its chest and head. It draws its legs in and dont want to use them at all. When I pick it up it is capable of moving its legs and has little strength in them. .One foot looks crumpled as well and the chick just throwed up. Im concerned for the chics. Help! Any advice?
