I didn't see it until OP just mentioned it today.Good catch, as always! @aart I didn't zoom in to look at the details of the fencing
Thank yoj, yes we are oretty much doing this but havent caught one! So disheartening. We have snap traps , himane traps and now put a bait station down but still they’re coming!I'm also in the middle of killing rats, but I'll probably be killing them off in mass numbers until the day we move.
We always put food away at night. Leave no leftovers out of any kind. Store feed in metal cans. Sweep and dispose of sweepings daily. Pen birds, use snap rat traps, electric traps, and just one bite poison where appropriate. You'll probably be better off than me, but I have to do all that and kill and kill and kill and kill in order to get eggs and keep ducklings and chicks (due to circumstances beyond my property lines). If you can make your coop impenetrable, do it.
We havent caught anything at it yet! The hunt continues! I cant set the traps either, husband had to do it lol.Sounds like weasel or mink. They are very tenacious and can quickly devastate a flock. We have had problems with weasels - fortunately they can't get into the coop but they did go after them when I chose not to put them in one night. I bought rat traps and a small Have A Heart trap but haven't been able to set them up correctly yet (long story lol). I read to use raw meat in the traps as that is what they are looking for. I have, however, been very vigilant about cooping the girls up EVERY night.
Good luck to your husband on the stake-out!! VERY interested to see what he finds out!
