My 1 1/2 year old pekin duck, who usually lays an egg a day, has been trying to lay an egg since Sunday morning. There are a lot of feathers so I think she may be molting ( I understand that they don't usually lay one then). But she sits around all day now just trying to lay, I felt of her stomach and I don't feel an egg (not a calcified one at least). She does get up to walk around a bit and to drink, but I haven't seen her eating. Doesn't act like she is in pain. Does she just think she has to lay but really doesn't or is it something more serious? Any suggestions would be appreciated. Thanks.
