3 yo RIR, walking slowly, tail feathers down sometimes, comb a bit dull, legs seem wider apart than usual. So I tried to read a bit about being egg bound, and yesterday we put her in warm water and tried to bathe her rear. I put on rubber gloves and ky and tried to feel inside her vent. This is the first time I've ever gotten close to the rear of a chicken that wasn't going in the oven. Her whole lower abdomen felt very firm, and it was difficult to get my finger very far inside of her vent. There was no egg showing, and her vent looked pink and healthy. She didn't mind the bath, although I didn't really like doing it as she had quite a lot of poop on her tail feathers. Maybe she's not grooming much due to not feeling well. Is it normal to not be able to get inside of the vent? Is it normal for her to feel very firm and smooth (no lumps)? I called IFA and the gal said to try some of their electrolyte/vitamin water. She said that chickens' health just tends to go downhill as they get older. I'd appreciate any advice.
