From farmerpete. Hi. I don't keep my newly hatched chicks in a brooder, never have. I keep all my newly hatched babys in a large plastic bin or refrigerator size box with a heatlamp at one end to keep them warm. I keep them inside until they start to try flying out of the box<about 18'' high> and when I know they are too big to get through the chicken wire, then I put them outside in a fenced in nursey thats 12x12x8ft. high, complete with covered nest boxes. The nursey also exposes them to the adult chickens on the other side of the fence. When they are big enough to go in with the other chickens , they are'nt attacked. I find this works best for me , but everyone has their own way thats successful . I have 24 yellow buffs,24 white leghorns, 3 black jersey giants, 2 guineas ,4 goats , and two pigs. We get $2.00 a dozen for our eggs and that is used to feed the chickens. We keep adding to our flock because we love chickens, and sometime we sell the chicks to other chicken lovers.
