We currently have 2 barred rocks (1 year old) and 3 RIR ( 2 years old we got from a friend last fall) all hens. Got 5 more Barred rock pullets about 4 weeks old now. The pullets won't be ready to go out to the coop for a month to 1 1/2 months based on size and temp. We free range during the day. I have 10 nesting boxes in the coop. I was thinking of bringing the little ones out and putting them next to the coop for a bit each day as the weather gets nicer while the big girls are still locked up. After doing that for several weeks maybe slipping the little ones into nesting boxes during the night. Any input would be appreciated!
