Thanks everyone
I actually looked up fisher cat noises on YouTube and saw some comments saying it could be a fox actually so then I googled it myself and found out that supposedly fishers are usually pretty quiet and no one's ever actually seen them screaming, most of the "fisher screams" are actually foxes. Sooo needless to say, I then Googled fox screams and sure enough, it sounds just like it. So I think it might actually be a red fox or two. I know we have foxes because I've seen them. I'm actually really glad because fishers are pretty scary. But who knows for sure what it is.
Anyway, you are right, it doesn't really matter what it is, I was more just curious because I had never heard that noise before. I also found it strange because we're not extremely rural, we're on about 3 acres set back in the woods but there's houses literally right behind us and condos around. There are cranberry bogs across the street but still, I would expect noises out in the country but not around here.
But whatever it is seems to have moved on.
And the chickens are secure and will be even more secure when we finally finish the new coop.
There was however a fox a couple months ago that came to visit a couple times and ran laps around the pen but couldn't get in. So I guess I'll just have to be extra careful. Good news though is right now they're in a dog kennel/run so my thinking is if it can keep dogs in, it can surely keep dogs (or other canids like foxes, etc.) Out.
