Help. So. Here's background
I have a barred rock. Approx 22 weeks old. She is in a mixed flock of 6 (Meyer hatchery asst ). They have a coop with perimeter fence approx 150 ft but I let them free range every day. Fence is just morning, evening predator prevention.
For last two weeks barred rock hasn't been free ranging with the others, she stayed closer to coop. I just figured it was getting colder and she was smarter. Last night, when I put them all in fenced area (the coop has solar door so it closes automatically) I noticed she was already in coop but didn't think anything about it.
This morning I went to clean coop and she was still there. I picked her up and she didn't even move (none of my chickens like being held). I brought her into garage and set her up in temporary crate. She took two shaky steps and hasn't moved since. I tried to feed her a grape and she wouldn't take it. She does sing a little song while I'm with her - but that's it.
She seemed lighter in weight than my other chickens
She's had marek vaccination
Eating (hard to tell. But even yesterday morning she went for their treats)
Pooping. Haven't seen any since I brought her into house (45 min ago) not sure which is hers in pen. But there was a runny yellow looking one (almost like dried egg color) in the coop - but could have been any.
I'm trying to find chicken vet in area. I know it could be respiratory but I can't get her to eat or drink so I'm not sure how I can even get her medicine.
What about the flock - they all look good now.....
Oh, and none of my pullers are laying yet.
