I had 3, 4 year old chickens . aragon got two of them. We just got 25 new chick's this week. My last big chicken is a barred rock. She is very lovely alone. Wondering if she might adopt since of the chick's? Should I introduce them now or later? Also my husband felt so sorry for the barredrock being alone that he went and got a welsummer pullet that's about 6 or 8 weeks. Now I don't know if the welsummer will integrate with the barred rock or if I should put it with the chick's.
