Hi, I am new to chickens, we live on a horse farm and this year at the feed store my daughter saw the baby chicks so I let her and my niece pick out 8. 4 Buff orpingtons, 2 rhode island reds and 2 black stars(sexlink)They assured us that these were all hens no roosters. Anyway they are now 4 months old and we have 2 roosters. Pretty sure of it because I researched online what mature hens and roosters looked like and they are definitely roosters. Since they are pets, my husband is going to build 2 more coups so everyone is seperate. My question is how hard is it to actually breed the chickens to get chicks? One rooster is a buff orpington the other is the black star(go figure) We were thinking of putting booth black ones together and giving the buff rooster a buff hen. Can someone give me advice about this or are we just wasting our time humoring our daughter?
