My 6 week old Golden Laced Wyandotte is breathing heavy, wheezing and just laying with her mouth open a bit. I can not get her to eat and drink on her own. I dropped a little water in her mouth and she swallowed, but it seem to make it harder for her to breathe. We changed from the medicated chick feed to pullet feed this week. I'm fairly new to chicken raising and don't know what to do. Right now, she is separated from the other 11 chickmates.
