So you are telling us that your roost with Sparkle and others in the really BIG coop. LOLMimddh, Punkin was one of two hatchery chicks too young ( a bit over a year ago) to go outside when fully feathered during a cold, wet spell. Yeah, that's the story and I'm sticking to it. Anyway, by the time I put them outside, Sparkle the House Silkie (another story behind her) was going out into the fenced garden every day but coming back into the house at night and any other time of day.
Sparkle was a "rescue" who had been in two other flocks but bullied and beaten up in them, so her last owner looked for somebody who would take her and let her be a house chicken. I picked her up about sixty miles away from my house, halfway between it and her last owner's property. She has hatched and raised four small broods of flock chicks in the house, since she came home with me. She takes her charges outside into the garden for their chicken lessons.
Beth and Punkin figured out Sparkle was coming in and out through the door onto the deck and they decided they would come inside too, to lay their eggs in the laundry hamper. Beth joined the coop crew like a normal chicken, but Punkin spent nights inside the house. As she still does.
She goes outside every morning - voluntarily - to spend the day with the flock, then comes back inside to roost at night on the audio bar on the TV set table.
Hence "Part-time" House Chicken.
