Thanks to a local bobcat we went from 6 chickens down to 2. I am a little unsure how we want to proceed. We intended to free range so our run is a little undersized. Right now the run and coop are both about 4'x8' and about 8' tall. First thing i'm concerned about is will 2 chickens be enough to keep the coop warm enough? I'm not sure how much chicken body heat comes into play for surviving winter. Secondly I'm a little concerned socially, Will two hens be enough to keep each other happy and active, I'm worried they'll get bored and/or fight more with just 2 of them. I am trying to decide if it would be better to find a good home for the 2 remaining hens and try again in the spring or if i should expand the run and try and keep my 2 remaining chickens happy and warm through their first NH winter.
