my run is about 33ft by 26 ft i think so its pretty large and i am really thinking about putting heavy duty tarpaulin over the top of it above the netting thats already there as i am getting annoyed with the run being muddy a lot but is this a good idea or not ?? , i had a bad case of red mite so i got rid of all my wooden housing and i converted those large storage garden plastic sheds they are working out well but they are not totally waterproof which is the reason why i got this tarpaulin as i was going to make a 16ft shelter over the housing and then drape it down the back of the plastic houses and then srcew them into the main wall to stop them blowing away but now i am wandering wether i could get away with just doing the whole roof instead as anyone else covered such a large area , i can pin it into the main fencing so it wont get blown away but with winter convering and maybe more snow that worries me with it getting stuck on top as last year it was bad enough with it being on just the netting .
