Thank you all. We are in Pahrump, NV, and we have had some cold nights recently. My son is 42, so I sometimes walk a fine line between advising and interfering. When he was setting up the coop, he made it known that he was doing this his way, so I have tried to keep in the background. We did have a few chickens once when he was about 10, but at that time all I knew was food goes in one end, eggs come out the other. I have learned a lot since then and am still learning now. Since we moved here 4 years ago I have wanted to get a few chickens again, but with one thing and another we got started rather late in the season. Personally, I would have waited another year, but once he had the coop all set up, he was anxious to get started. Since it is so late, I have no problem waiting til spring for eggs and if we get new chicks early, we should be doing nicely next year. He doesn't know whether he wants to brood his own eggs again, but if he does, we both know more this time and the timing for it will be better than this was.
