We have two hens. A Barred Rock and an Ameraucana. First time chicken owner. We are building a coop now for them. We've chosen to put the coop in our screened lanai. Reasons being.. protection from the elements and from predators. The coop will be 10' long and 3' wide. Questions are..Do they have to run loose in the yard or can they stay in this coop. We are planning on putting either hay or pine shaving down on one end and possibly putting some squares of sod on the other end so they can do their pecking. My worries on letting the out are.. them flying away, predators.. Cats etc, and the biggie.. Getting them back in the coop!! We have a large yard with a pool. I'm worried that they won't find their way back to the coop OR that I won't be able to catch them and get them back in it if they don't find their own way back. Can you give me some thoughts and ideas on this please!!!! Thanks so much for any insight on the subject!!!! Btw.... I'm just crazy about my Daisy and Olivia!!!! They're the sweetest chickens ever and will climb right up on me!!!!
