4days ago, my chick started showing symptoms of weakness. At first, she started eating less of her starter feed. So we started giving her egg yolks. She ate the egg yolks very well but today, she wouldn't even touch it. She has also stopped drinking/eating anything at all today and we had to resort to feeding her ourselves. She has gone from 39/38g to 32g in the past 4 days. She is very weak and cannot walk around. Now, it seems she cannot even support her body weight/wings. The first signs were droopy wings.And then everything else followed. She should only be 2 weeks old maximum. Her wings look huge for her body and her body is tiny. :-( She looks like a 3 day old chick with huge wings. She also has very watery poop. Her vent looks sort of swollen, red and protrudes. She used to get poop all over her bottom but we have cleaned her up and applied a little olive oil which has helped at least to keep her clean. She doesn't seem to be in pain but is getting weaker and weaker. We have now separated her from the other chicks and gave her a stuffed toy to lean on. Do you think she has Coccidiosis? She has been in the dirt in the past. She used to be so healthy and active. Please help!!!
