THought I had a broody - she was sitting in the nest box all day, but no egg from her. Decided to take her out & try to get her to eat some and get some water too. She takes a few steps outside into the run and poops - but it was runny, and looked like it had yellow yolk in it? What could this be, and more importantly, is there something I need to be doing? She's moving a little slow for her, but other than being in the nest box, I don't see any other odd behaviors. Thanks for any input you might have!
