I have a young hen who hasn't started laying. She spent a lot of time in nest boxes without results. I figured she was a 'late bloomer'. About a week ago she was acting distressed, so I massaged her, looking for a stuck first egg - nothing. So I injected some coconut oil into her cloaca to possibly loosen things up. She seemed to be OK. The next morning, her complete oviduct was in the poop tray below her roost!! Her behavior has been completely normal since then. I had been worming the flock prior to this. none of the other birds has a problem; all are very healthy. Any ideas?
