[SIZE]3[/SIZE]Our pullets are 15 weeks old and looking more and more like adults. We have kept them locked out of the nest boxes while they learned where to roost Im thinking we have another month before we need to let them in to the nest boxes. This would make them 19 weeks old. Any thoughts? When do you switch to layer pellets? They are on an 18 % grower ration. They also get kitchen scraps, chick grit and free range for aprox. 90 min a day.
