Haven't got the chooks yet, actually, but am trying to think ahead! I have just ordered a really thick, insulated rabbit hutch cover for the bunnies and was wondering whether it would be a good idea and/or necessary to get something similar for the chicken ark?
I mean I know rabbits are fine in cold weather really but I feel awful for them out there especially if it snows or something, they have got each other (3 of them) and the hutch is ok for a hop about but they can't run to get warm.
Obviously chickens might operate differently. But what do you think...there is a guy on ebay who does made to measure insulated covers.
Don't do a blanket, its important that chickens have good ventilation in their ark. They go down with all sorts of respiratory problems otherwise. I don't even shut the ark door at night and they've always been fine.
