One of my 13 week old cochins hasn't been herself for a few weeks. When we got the pullets at 4 weeks she was the most afraid of humans, the biggest (or at least fluffiest) and most outspoken about issues like being picked up. Lately she's been quieter, doesn't fight being picked up, and also is now the smallest of the coop. She seems to sit around more than the others and moves slowly, and I noticed a few days ago that her butt feathers were poopy. I've self-diagnosed her with worms (there are no vets nearby and my work schedule wouldn't allow me to bring her to one until the weekend) and ordered a de-wormer online. Is there anything I can do to help her right now? Yesterday I gave her a bath to get the poop off and have her living in confinement inside. She's eating her normal feed, her water has ACV in it, and this morning I gave her some garlic/yogurt/oatmeal treat which she ate right up. I just feel so guilty that I didn't try to figure out what was wrong with her when she first started acting off.
