When I let my chickens out of the coop two days ago, one of them was really sluggish and her comb was drooped to the side. So I brought her in and have been keeping her in our laundry room for the last two days. Her poop was watery with a little white and green mixed in. Not much solid poop at all. I thought she might have sour crop or impacted crop, so I've been feeding her yogurt and some eggs with vegetable oil mixed in. Her appetite has been okay and she's drinking a lot of water. She did show a little improvement overnight last night. I am starting to see a little more solid normal poop mixed in with the watery stuff. Just a little though. Also, she's breathing with her mouth open. She's 15 months old and she hasn't had any problems before. I'm kind of worried about the mouth breathing. Does that indicate a respiratory infection? I know that can be very dangerous. Thanks
