well I've got what they call barn yard mutts , they are all kool in there own way I have 16 hens an 1 roo ,they ( hens) are laying 10 to 14 eggs a day , an its been down to 26 below but we are in a warm up at 16 to 20 above, my roo has had a little frost bite ,but is doing fine I do have heat lamp in the coop an its un insulated 8x8 at 8ft on the front an 7 ft. at the back out of 16 hens I have 1 broody an we have let her keep a few egg's under her.so I would go with barn yard mutts .
We will be closing on our new home about 2 weeks after the chicks arrive, so my husband should have time to get the coop and run set up. We have a large shed on the property we are converting to a coop
