cant you catch them in the walls in the day micky....or is it to exposed ??
i love taking them out the walls ...my little lurcher bitch is mustard at marking them in the walls...you got a spaniel i think ...will it not mark them...few purse nets after shes marked and try and get it out....small pry bar often helps...
years ago woodga was telling me this meathod ...he had a thin sharp bar ...like a knitting needle that he would line up through the gaps in the wall then skewer the rabbit through the head then move a few rocks and remove the bunny...sound feasable i have never tried it
