Last June, I bought 10 chicks. BSL and RSL. I have a huge old chicken house but it wasn't in shape to accommodate guests at the time. I kept them in a 10x10 dog pen lined with poultry netting. I have since fixed up the chicken house, where I house 5 laying hens and one white leghorn rooster. I absolutely love my chickens and I have one hen (lorp) setting. The first time I've had one go broody so I am excited about the experience of new chicks. The nesting boxes are about 3 ft. from the floor and I am concerned that the chicks will fall from the nest and how the other adults will treat them. Should I place the mother hen and her chicks in a coop by themselves for a while? I also have 4 SL pullets that I have separated. At what age should I try to house them with the adult chickens? They are 6 wks. old and eating chick starter crumbles.
