I've raised chukars for a few years and it wouldn't supprise me if you could tame them. I am the one that feeds our chukars most of the time and I tend to linger in the pen with them when I do. It doesn't take them long to realize the difference between me and my husband. They don't run/fly away when I come in the pen and walk around. I like to sit and listen to them coo. The same thing goes for quails. I worked with them (quails) more and I could get them to eat out of my hand. It really helped when it came time to sell them cuz they were easier to catch. lol If you can tame them (chukars), you won't be able to let them run free cuz they will take off. I had a few escape from their pen and they came back to visit the ones that were still in the pen but I couldn't get near them even tho they were used to me. As another poster said, a heat lamp may not be a good idea. Keeping drafts down to a minimum would be best. Chukars tend to do good in the winter where I live (central illinois). It gets below 0 tho not days and days in a row, except this year. I hope the chukars survived in the wild this year. My pen has windows facing the south so the sun tends to warm up the pen (somewhat) on really really cold days
