I have a flock of one rooster and 15 hens. After 1 unsuccessful hatch and 3 small hatches I have 7 new chicks with about a week apart between each hatch and the first hatch was in November and the last was dec 1st 2014. When and how would anyone suggest I introduce them to my other girls and also I may have one or 2 baby Roos as well which with the amount of girls I would want at least one but I know my rooster was picked on that's why I rescued him and his tail feathers just started coming back in. What would anyone suggest. And some of my hens had been picked on when I had taken them in. I want to make the transition as easy as possible. They are in the house now was thinking maybe building a brooder box with chicken wire and placing it in the coop till they are big enough? Thinking if then hens see them for a while first when they are bigger the transition would work out better?? Any advice?
