We have 5 older pullets, 3 barred rock 1 orpington and 1 rir, that are 15 weeks... they are eating organic grower feed. We just got 3 more chicks that are 3 weeks old. In 4-6 weeks I hope to have them all in the same coop. The babies are eating organic starter feed. I’ve red that some of the pullets may start to lay in 3-4 weeks so if i change their feed to organic layer feed.... how do i keep the chicks out of it? I leave the feed out until bedtime. Any advice is appreciated! Ty!
