I have a 2 year old hen who seems to be in some sort of distress. Yesterday evening I noticed her standing in one spot all puffed up which seemed unusual. Then at 8:30 when I went to lock up the coop, I peaked inside and she was sitting inside one of the nesting boxes, again strange. Then this morning when I let them out she slowly walked passed me all puffed up and I noticed she was trying to push something out. She had something narrow and white that looked like a stick sticking out of her with a trial of poop down her feathers. Looks like what ever it is, is some what stuck. When I picked her up to see if I could assist in removing it, it went back inside. Any suggestions?
