Goose, what did he use for the ends and the tops? I have had the fighting issue also...I have one set of kennels with 4"x 4" wire that i had to hang sheets of metal between each kennel and of course the its rusting now. But the other set of kennels has 2"x 4" wire and they can't seem to get their muzzle through that.
The ends we just butted to the front and back post of the pens in between kennels and we filled the blocks with concrete as we went and we just took a mortar trowel and smoothed the concrete on the tops...
