I have a hen that I saw yesterday has a kinda lump?bump? I really don't know what to call it. It's in the back of her her right buy her vent. I did think it was a egg that was maybe fixing to be layed. That's what it looks like kinda sticking out the size of a egg. Has any body ever seen this. I would think I would have seen it before now if it was there. Oh, I didn't see any place on it to drain out either. Can you tell me what this is? She is a young pullet(light sussex) just started to lay.
