I just bought four 20-day old chicks, 1 white leghorn and three Buff Orps. We are keeping them in a brooder for now, but since we live in AZ, is it warm enough for them to be outside? It is about 55-60 during the day and 35-40 at night. What about the summer? Will they adapt to the heat? Will these two breeds live harmoniously if they are the same age? I am so excited to start this and my 4 little kids are too. Any advice you could give me as a new mama?
