My pullets are 18wks old and one started laying yesterday, another, today. I found both eggs on top of the nest boxes. I put wooden eggs in two of the nest boxes to try to incourage them to lay there. I just put my two older hens in with the little girls and one of the older ones layed in the nest box today. Will the little girls just learn their way around or should I do something else to encourage to use of the nest boxes?
