When we moved I didn´t have a secure coop yet and we just had 1 chicken (Whitey, about 2,5 years old), she slept in her little prefab-coop in our hallway and later in a storage closet. A week later we got her a friend, not ready yet with the coop, but the chicken-guy came that day and I didn´t want to wait another month because she was alone. ( the chicken-guy comes once a month from march till september in a truck to every town here, you can order p.o.l-pullets, roosters, ducks, quail, chicken food and other stuff, very convenient, and dangerous if you don´t have your chicken math under control

)
Of course integration wasn´t easy, so our new p.o.l. pullet (Suzy) slept in a crate in our not ready yet living room, it took another two weeks before their coop and run were ready, and after they moved there, they came walking in the door every day to demand a snack...
Now we have 3 chickens, our sweet Whitey died and we got Suzy 2 friends, Mona and Lisa, and Mona is terrified of the door so she starts to scream as soon as Suzy walks to it... so no longer do we have chickens in the house...
