thanks....I wasn't sure what to do exactly so I used straw bales but I have had a couple stinkers squeak through the bales so have stuffed the joints with small logs and now have graduated to a 2x6 blocking the entrance as they were squirming there way over the 4" fence post I had laying across the entrance. I love the Costco kennel/dog run set up...it has been so valubale as a quarantine, dog detention, lambing jug and now whelping pen...plus it is 15' off my bedroom window so I can shine a flashlight and check on them in the middle of the night, without leaving the house! I know you all wish you would have thought of that one!bj taylor said:what a great nursery set up.
