I have been keeping my four bantam silkies in this coop since last June: https://www.walmart.com/ip/Boomer-a...MIhcWdsa_X4QIVDp6fCh1wiQ24EAkYBSABEgI3KfD_BwE They've done really well in it and haven't been crowded (or at least haven't shown any overcrowding behaviors and have been laying really well), but I just acquired a Speckled Sussex, a golden laced Wyandotte, a golden laced Polish, and a Black Jersey Giant (all day-old chicks) last week. So now my flock has doubled in size. Right now the chicks are in a brooder in the garage and I am in the process of doubling the size of my chicken run to accommodate the new hens, but I totally forgot in my plans that my original coop is NOT built for that many chickens. So I've basically screwed myself into a sort of major carpentry project (or purchase, in any case). Does anyone have any suggestions for me as far as building an add-on to this setup? The birds have a wrought iron fenced run covered with avian netting that they are loose in during the day, so they have plenty of foraging space. My concern is the wet winter months when everyone will be cooped up together. I'm especially worried for the Jersey Giant due to her impending height.
