We got chicks yesterday from our feed store - according to them we have 3 Americanas and 3 RIR although one of the Americanas I'm thinking might be a white leghorn looking at pics. Anyway right now we have them in a wire pet crate with hardware cloth around it and we will be moving them into a large cardboard box today. According to the feed store they are 6 days old today. My question is - How old do they need to be before we move them out to the coop? It's in the 50's here at night and 70's here during the day. We'd put the heat lamp out there for heat. The three sides of the coop are plywood about 3/4ths of the way up and we will be putting chicken wire above that. So what age can we move them out there? Can we put their box out there with them in it and the heat lamp?
