I have a sneaky suspicion that my year old hen, Marilyn, may be egg bound. I noticed last night she is very lethargic and just sort of stands around or lays down. She slept on the floor of the coop in a bedding nest I made for her all night last night. This morning she is still just standing around, in a sleep like trance. She's also had watery diarhea for 2 days. While I was checking on her she laid a soft shelled egg, like a little water balloon. The diarhea is just like water and there is no odor at all to it. Anyone have any ideas?
