I have a bantam hen whose crop seems slightly larger than what I believe is normal. I've only had her for a couple of weeks, so I'm not sure but she's moving her neck in an odd way. Sorta stretching it to the side. I took her out and massaged her crop and it isn't rock hard but seems like it has a ball in there. Her bedding is hay (which I am going to switch now that I've had this problem!!) So far I've massaged her crop and put her in my isolation crate with pine shavings. I removed all food and am stopping by the grocery store to pick up some plain yogurt. I plan to give her some yogurt and some olive oil tonight after work. Is the neck stretching a sign of an impacted crop? Also, the reason I'm using hay in the coop is because it has a wire bottom. I wanted to cover it but wood shavings will just fall through. Other suggestions of what to use in a coop with a wire bottom? It's not normal wire, its actually very thick - some sort of steel or something. but it does have holes large enough that wood shavings won't work.
