Hi there, welcome to BYC!I have some Cornish cross chicks that are 4 weeks old and they keep dieing.
Their belly are dark and they have a lot fluid in their belly around their organs when I cut one open . They stop eating and drinking and their feather are fluffed.
thanks for the vote of confidence but I am really weak on diseases, diagnosis and cures/corrections. I haven't even had a CX die on me unless it was one well beyond its very short lifespan (that's 10 weeks) because I wanted to breed her.
