Do domestic cats pose a big threat to adult standard chickens? We have a very small neighbor cat (Max) who spends all day bumming around our chicken pen watching the chickens. It makes DH uncomfortable (though, he's never liked this cat anyway) but this cat is not large, is not bright (DH pitched a rock at it once when it was younger... just to scare it.. but accidentally got it on the head. He was aiming for just in front of her.) For some reason, she LOVES us. When I'm in the yard she spends the day with me. I noticed her around the pen, and it appears that she's more interested in just watching the chickens than stalking them. She lounges in the sun, and sometimes when it gets too warm, she'll lay down right next to the fence where the shade tarp is and where I have my guinea run right now (until they get bigger). Strangely enough, the keets will sometimes lay down next to her and she doesn't show any notice. So, I'm fine with her. I'm curious about the other 4 cats my neighbor has. Though I've not seen them too much around my pen (other than to beat up Max, who then spends her time in a laurel hedge cuz the others can't climb it ) I am aware that they are normal sized and wonder if they'd try to go after a regular sized hen.
