Protecting Coop from Weasels/Minks!
You need to seal off / secure all small openings. Them lil devilz squeeze thru some mighty small cracks. Another good option is to protect your coop with an Electric curtain. You would have to get creative in installing such, but it can be done. One zap from 15,000 volts sends the message. It does not kill them, just sends them for the woods.
Here is the energizer I will be using to protect my Pigeon loft. A raccoon finished off 7 of my Eagles.. ( that is what my grandchildren call them( "Grandpa's Eagles")
About $35 for the energizer. The wiring, netting Insulators of course will vary in price according to your needs.
