My buff Orpington Sunny is super lethargic I pick her up and put her down and she barely stands and lays down. Her comb is extremely pale and she usually runs up to me and she didn’t and then I knew something was wrong. Her two other flock mates are fine and crazy as usual. She laid an egg today around 11-12 that’s her usual time. She looked fine this morning at 7am when I let them out of her coop. My husband said he checked on them this afternoon and they were al happy. I went down there at about 8pm this all started happening. I checked her vent seems fine and healthy. I checked her body it seemed fine too. Didn’t see any mites. She isn’t fat, she’s about 3-4 lbs. My flock was attacked by a raccoon 3 weeks ago and killed 4 of them. If she dies I’m going to be absolutely devastated. Please help! Also! They have hay in their coop which I got from a feed store and they ripped it apart. She won’t even roost I put her in the nest and she laid down. What’s going on?
