I currently have two summer coops set up. One for my silkies and one for my other hens/rooster. My husband is building a new insulated coop for the winter. (I'm in Canada where it can go as low as -40) I was planning on putting them all together in the coop to keep warm but when I spoke to someone today they told me that silkies do not do well in cold weather! So now I'm panicked! Are silkies that much different from other breeds? I was planning on putting a heat lamp in there thinking that together with the heat from the other chickens they would do fine.
