I have a black australorp hen who is about 1 year and 3 months. This past Sunday evening, I noticed her just standing in one place at times with her eyes closed while the others scratched around. She kept doing this on and off. Her feathers weren't ruffled, just looked like she was napping in place. I noticed a little bit of runny poop on her butt feathers and noticed that her poop was a little smaller and more wet/oily. The next morning, she was doing the same and I also noticed her crop felt like it hadn't completely emptied during the night. It wasn't huge by any means, but didn't feel completely empty. I took her into the vet that afternoon and of course there wasn't anything that was obviously wrong without doing a bunch of extra tests. She was not egg bound. I pointed out her crop to the vet, but he didn't think it was that big, or anything to worry about. The vet gave me the antibiotic Trimethyl Sulfate to give to her in hopes that would take care of whatever it may be. She seems to be more energetic and is scratching around with the others; however, I still notice in the mornings that her crop feels a little full compared to the others. She is still pooping some, but it definitely isn't her normal poops. This morning while checking their poop under their roosting bar, I noticed that she had laid a really soft shelled egg that was broken on the floor. She has been wormed recently and is drinking and eating on her own. Should I go ahead and try to treat her for an impacted crop by using the plain/non-stimulant Dulcolax? I have read @TwoCrows article on treating an impacted crop. Is this okay while on antibiotics? I wouldn't see why not, but not 100% sure. Any advice on what I should be doing would be greatly appreciated!
