I would agree with Tomo...
Rabbits up my way get bigger and fatter as the season goes on and a fell rabbit can weigh good few pounds more...
As life long cumbrian says some old bucks are tough as old boots... Seen me rip one in half, trying to get its jacket off..
Seen some unusual rabbits in one area must be hybrids that have breed with a domestic Dutch rabbits, they must of been realised or escaped ..
Seen blacks, black and tans , sandy coloured and tortoise shell type..
