We purchased a Buff Orpington at an auction last night. No way to see them until they're holding them up. She is a huge girl and looked really healthy. It was late when we got home last night and she had this little rattle but we thought it was stress. This morning she is really rattling. We finally picked her up to see if her legs were okay (they're not overly gentle at the auction) and she seems find but extremely lethargic. Her eyes are pretty perky but she's sleeping a lot, we've gotten her to eat a bit and gotten some water in her plus I've gotten a little olive oil extract and acv in her. We've got her in a separate little cage out in the sun. What else can we do? We try not to do a lot of medications so I need advice for holistic things first.
