Hi everyone!! I am new to this site and new to chickens!! I have 6 babies, 3 red 3 black sexlink, all doing great! I have them in a pen with a heat lamp in the garage. I plan on moving them to my friends farm to free range on 25 acres. But of course we did not plan well and have to build something for them before they can move there. So I ask, if I let them go in my fenced yard, will they come back to the pen? If I make a ramp for them to get into it? It's currently on the ground...Ty so much for any advice!!
