I have an adult female corn who has been acting weird lately. She has been refusing food, nose rubbing and constantly cruising her tub. I have had her about a year and have not bred her myself. She is a little swollen in her lower half and looks almost gravid. Is it possible that she is gravid and wants to lay. I read in a book that her actions could be a sign she wants to lay. What do you think. She's in a 42qt tub in my rack and the temps and humidity are right on. She doesn't seem sick, just restless.
