I only have bantams, but an acquaintance was looking for a good home for her 3 chickens....I thought they were all silkies. She brings over 2 silkies and one big ***** Americana, lol. For someone who has only bantams, a standard chicken is gigantic. My coop isn't really meant for a big girl, being that the water nipples are sized for the height of bantams. The nighttime roost is also meant for bantams, being close to the roof. So, she tells me that the 3 chickens usually sleep in a plastic box, the larger chicken doing the same thing. I built a nice "ladder" type roost for them today and tonight, I see the large one perched on top of the indoor water system, the 2 silkies taking up residence in the nest boxes. So I know silkies do not roost per se but prefer flat surface, but should I try to manually move the big girl onto a real roost? She looks real uncomfortable and frankly, pooping on the wrong spot!
