I have 5 RIR and an EE that were hatched on 9/8 that are in a brooder together. this morning I picked up 7 packing peanuts and 7 White porcelain d'uccle bantams they hatched on 9/15. These guys are going to eventually all be in the same coop and run together. (the hens definately and the roosters until they are old enough to sell <or eat>). When can I put them together in a larger brooder?
