Hi. We have three 25 week old Ancona's. 2 females and 1 drake. (We also have 4 female ducklings to even out the ratio, but they are not in with the big ducks yet). One of the Ancona's has been laying for several weeks now but the other one has not started yet. Is this normal? I am wondering if maybe she won't start laying until the spring now. Anyone have thoughts on this? Thanks.
