Hi, new to the backyard chickens community but I have been reading post for a while. My story is that I am a first time duck owner and have 2 female Peckin duck about 6 months now. They are from the same brood. The problem is only one is laying eggs and the other isn't. I have looked everywhere cause I know they are prone to hiding them but I don't see anything. I wouldn't be as concerned but they were born the same time so I figured they should start at the same. Is this something I should be concerned with?
