I have a RIR that is 9 months old. She is a happy chicken but some days (today for instance) she walks around really crouched down so low that her belly is practically dragging on the ground. When she does this she also slightly wiggles her back end. Sometimes she'll walk sideways while she is doing it. I've checked her bottom and nothing looks blocked or backed up. I'm not sure if she is laying or not, I have 7 hens and usually get about 4-5 eggs a day, someone isn't but I'm not sure who. All the poops under the roost look normal as well. Has anyone experienced this??
