I would like to start by saying that I understand it is not necessary to bring silkies "indoors" during the winter months and that they can certainly remain outside in a well insulated coop with some extra straw to help keep them warm. I have decided this year to bring my small silkie/frizzle flock "indoors" and keep them inside my shed during the cold winter months. I have a few reasons for wanting to do this, one of which is because I want to separate them by who I want bred to who. So I have a lavender pair, a splash trio and two frizzle hens. I had plans to keep them in pairs (well except for the splash group) in a couple of the shipping crates that measure 2'x3' but after researching I realized this isn't large enough space to keep two in and it is recommended I give at least 5 square feet per bantam. Right now I have two of these rabbit hutch/chicken coops from Tractor Supply.... http://www.tractorsupply.com/en/sto...heavy-duty-chick-n-hutch-2-4-chicken-capacity They measure 42-1/2 in. L x 28 in. W x 39 in. H (3.5ft x 3.25ft = 11.3 sq ft) Would this be a large enough living space for 2, possibly 3, silkies for just the few months they are going to be kept inside the shed? I want to keep them this way because when the splash hens and the lavender hen start laying, I want to be sure the splash were bred to just the splash and the lavender was bred to just the lavender and come spring time I have eggs to hatch that I know for sure what parents gave me.
