so in the midst of the great raccoon debate, unless I missed it, you've had no further attacks. Did you do anything diff to shore up security?
Maybe close up a section of brooder so you can lock them in at night as we do with coops? Himself argued that ours is build on sleigh runs that would require 10" of digging to get under, but I still ended up putting a board down for my own peace of mind. It makes it easier for me to walk on and do deep litter method. - Now that I'm cleaning it out, I probably should have put tile or something over the board,

but it's still sturdy.
The run sides are open w/hwc, but he put salvaged steel pole barn siding on the sides of coop and roof so they're locked down at night.
That 2 wk period I mentioned when we had a run on raccoons, they were able to climb up hwc and walk on roof, but none found a way in.

Re the one he drove 20 mi away, no, I don't think she made her way back. For one, there's a lot of highway between here and there, and two, after staring at that many of them in a trap or tree right outside your window, you realize they don't all look alike. She had a sweet face and didn't get pissy until he picked up the trap. Some of them sounded ready to rip our faces off before we even went outside, and one was trying so hard we wld have put money on him tearing the trap apart to get out. Hopefully this will be the last of your attacks.
