i left my door open not so long back, and had four on the run, at this point they were new to me and only one had been worked! i live on a farm and i was hell to find them, one was in the warren i work most, not the one i had worked though. (rabbits were bolting thats how i guessed) My working one was actually curl up in the dog bed next to my dog. one was in the chicken hut eating eggs and the other one was chasing a chicken.....it toomk over 8 hours to find them all.....i was gutted until i found them.....good luck finding them!!!!
