I've got a few chukars and was hoping to get some eggs from them during this winter. What does that take? Do they just need light or do I also have to keep them warm? And how warm? Also, is making them lay hard on them? I know they need some rest, but I'm not sure how much they really need to not put too much of a strain on them. Honestly, I'm not sure what sex they are, so whatever I do I might not get any anyway! lol Thanks!
