I have a beautiful bantam Salmon Faverolle rooster, Benjamin, and 3 gorgeous standard Black Star pullets (almost hens, yey!) ..Piss n' Vinegar, aka. PV ..Louise, aka. Weeze ...and Hannah, lovingly called "cry baby" ...and they all have a run in the backyard. They also have a coop, but I am fearful that the darn raccoons will get my babies ...so they have been roosting in our garage every night. Recently, my coop was reinforced and even *I* have a hard time getting into it ..lol ....so I am considering putting the "kids" to bed in their own coop from now on. (It would save some of the poopies they like to plant on my washer and dryer, too ) Should this be a problem? Will they have an adjustment type thing to go through? Does 45F - 55F warrant a heat source inside the coop or will they snuggle like they do in the garage? (I'm in San Francisco Bay Area ..short driving distance to the water) Btw, they get plenty of extra yummy stuff to help them be at tip top health ...and they are all fully plumed now (Ben moulted soon after I got him, a few months ago). BenBen: "Sleep outside... but why, Mah??" PV: "You juss mean 'dem, hunh Mah... not me... I sleepin' wif YOU.. right, Mah??" Thanks!
