I went to the Boss Buck site, don’t see what you could be using for protein?
If you’re going to end up with their protein ports, here’s something I did to get medieval with the coons. Besides the screws, you can buy the metal teeth plate things at Home Depot. I actually needed another layer behind the ones you see. It really cutdown on the nefarious activity but a couple of acrobats still figured out how to hang.
So just to ask, what result are you looking for to make the decision to keep feeding protein if this is a test?
