Our two GPs are outside in a combined hutch/run. I put them to bed and get them up and in the day they're happy in the run. I keep a pet carrier in the corner filled with newspaper and hay and they like to have a lie down in there after lunch. 
But so far the days have been largely dry. Just wondering what to do as the weather gets wetter? I know wetness is not good for them but don't want to coop them up all day. Are run covers any good/not too pricey?
