I have a sick chicken on my hands. She's close to 3 years old.
When I went to put the chickens away in their coop last night (they are free range during the day) I saw her in the goat enclosure laying down with her eyes closed. I was convinced she was dead. I went over to deal with disposing of her body when she awoke and ran from me. I was able to catch her and check her over. No lumps, bumps, or injuries. Doesn't feel egg bound and her crop is soft.
Here are her symptoms:
1) not eating
2) not drinking
3) stands around with eyes closed
4) when I attempt to pick her up she does react appropriately - wants nothing to do with me
5) last night she slept in the laying box (usually she roosts with her friends)
I thought this morning she'd be a goner, but she lived to see another day.
When I got home today I saw her around the other chickens but she was just standing with her eyes closed. I threw out some scratch, which she usually lunges for, and she just sat there.
Her poop, what little I did see, looked a little suspect - loose and clear with some white color.
The other chickens have taken notice. One chased her. I guess they know when the weakness and illness are showing.
I know this is totally vague. It has me stumped.
