12 pullets

I have 15-week-old Rhode Islande Reds and Mixes (5 pullets and 1 Roo) and seven 6-week-old pullet chicks (Buff Orpington, White Leghorn, Barred Rock, Red Sex Link, and one Easter Egger) I have set up a makeshift cage next to my bigger chickens run. I started putting them next to them yesterday...
