Hello. My wife and I are going to build our new home North of Sparks ( on Grass Valley road) soon. We haven't raised chickens before although as a kid I helped feed and picked up eggs as a child. I am to be 55 soon and my wife is a little bit older than I am. We have had many different pets over the years( we had 27 at one point) including cats, dogs,birds,tortoise s, lizards,spiders,snakes, and chinchillas. I'm currently doing my homework to find out as much as possible about chickens before I jump right in. My main question is what breeds are the best for standing the heat but also the cold ? I would like to raise some for eggs of course but I also want to raise some for meat. I have so many questions as to how many square feet does each chicken ? What's the best feed, what extra vitamins will I need to give them? The whole ball of wax. Thank you for the assistance.
