Thanks for all your tips. I think they're starting to wise up, none caught last night. But I found that they're hanging out under the wood pile, or at least that's where I saw three, one of which I killed. So, I'll put bait there as it's outside of the chicken yard. I hesitate to put poison in holes inside the chicken yard as the chickens could dig & uncover it during the day.
Last year we had red squirrels & caught 1 or 2 of them, haven't seen any more, but no bird feeders now. Probably still around, just not visible. Saw a fat gray squirrel this winter.
Found one small pullet with what looked like a rat tried to bite it's head last night, but she escaped. Going out soon to move young pullets into a pen on pasture away from the "brooder barn". Just will leave cockerels in there until I can finish my other pen for pasture, just got the hinged roof "door" left, roosts then can move them out too. Lost two meaties, even after making the adjustments to secure more! They were like 5-6 wks old, so a good size. They were moved out today as well.
One I get everyone moved out, I can take out litter & add flooring of some type, as that's how I think they're still getting in.
