My Rhode Island Red, Merida, has a shriveled comb, poopy butt, and is lying down a lot. Found her in the coop this morning lying under the perch with lots of chicken dander on her back which means the other birds were up there shaking their feathers over her for a while. She's been this way for a couple of weeks. She can walk, but seems to like to stand on one leg (checked feet and legs look fine). Looks sleepy-eyed.
We used to let the birds have the run of our yard lawn, but cut back their range a few weeks ago, so that they can only go in a more limited area near their very large coop. About a week ago, I noticed our birds were eating falling leaves from a plant they've always had access to, but probably never ate before when they had the run of the yard and could eat the grass. This plant is toxic-- it's called Blue Potato Bush (little purple flowers). It's apparently not technically a potato, but is still poisonous. I only realized it was toxic about a week ago and removed it, but this hen still looks bad. Wondering if there's anything I can do for her. I did give her some charcoal as soon as we realized this might be from eating this plant, but of course she may have been eating it for quite a while. I didn't actually see her eat any but saw the other hens eating it-- funny enough the others are fine, thank goodness. We did have one other little silkie who got sick a couple of times and the second time she died. Now in hind-site, I think she must have been poisoned from this plant too. She foraged more than the others, because she was at the bottom of the pecking order and had a hard time at the feeder. We always tried to had feed her every day just to make sure she got enough food.
So, any tips to bring my sick bird back to health? Last time we brought a sick chicken to avian vet it was over $200, so we want to avoid that if possible. Also not even sure it will work she's been sick so long. If it's poisoning that occurred at least a week ago, I'm hoping we can just do something to support her and build her back up.
I wonder if I should give further charcoal or if it makes and sense when it's been this long, or if I should force her to drink some water with a dropper? I've given medicine and food with a dropper straight into the crop of another hen who was sick before, so know how to do that.
