Hi, i have 9 baby chicks between 4 and 6 weeks old. They are australorps and barnevelders. They are reared under a brooder (ecoglow) and kept on pine shavings. Two of the chicks are still the same size as a 1 week old chick! The only feathering they have is wing tips. One chick appears completely healthy. The other has its eyes closed, bit crusty around corners of beak and a dirty white butt. It still rushes out to feed when goodies arrive (has full crop), drinking etc. Does spend a lot of time under heat source. Its been like this for 2 weeks...not appearing to get any worse. ALSO i have them all on medicated chick starter AND amprolium in water but they continue to have blood in poo?? Any ideas? Thanks bec
