Here's the rub I've had 3 hens (2 RIR's and a barred sumpin or another) for a little over a year we are going to get 3 americana chicks today. Will the big ones actully harm the babies or just be mean to 'em? I would like to sneak em in tonight when they are roosting. Or should I keep 'em in a little cage in the backyard with the others, or just let the chips fall where they may and just let 'em free??
