I have a couple of duck questions. At what age does a hen start laying eggs? She keeps going up to a small hollow at the base of the tree and quacks while staring at it. I have one who is 6 months old. I do believe she is a Peking. And will a male attempt to breed a hen if she is not ready to lay? Also does it matter if they are not all the same breed? I have a male Khaki Campbell and a female Peking.
