I have 11 White Rock adults right now - 2 roosters and 9 hens. We are going to be adding 11 more hens to our flock. We hatched these, and will be putting the hens in when they are older - about as big as the adults. We currently have the newbies in a pen right next to the adults - with only chicken wire separating them. I wanted to let them see each other to get used to them.... How old should they be before I put them in with the adults? When should I do it? I read somewhere that adding more chickens (or taking away a "head-honcho") can really upset the pecking order and cause great stress. Someone else told me to do it at night when they are roosting. They will have plenty of room and feeders/waterers... but I'm concerned about putting them together. What is the normal process?
