They are only about 2 wks old and I have been treating them for Cocci with Corid...well now I think I have a different problem and the one runt just isn't growing at all...and I don't feel her crop emptying. It feels more fluid like then the other 3 chicks in with her and it's probably bc I'm not seeing her eat regular food and she's only taking in the yogurt I am offering her every couple hrs...I'm afraid to force her to drink water bc I read it can make it worse? What can I do? I have zero experience with crop issues...thank you. She's just getting smaller and smaller by the day it seems and everyone else is doing just fine.
