They are in the walls, the ceiling, every place possible. When I kick the wall, they all come running out of one hole into another. I had a wooden gravity feeder that they had eaten the back out of. I got rid of that, went back to my metal hanging feeders. I also bought a flock block, so my birds wouldn't be bored during rainstorms and what not. The mice hollowed that out completely! Last year when I had no flock block and no wooden gravity feeders, I had a tiny family of mice living in the cement block that the water was on top of. There was maybe...7-9 mice... Now, I swear it's gotta be around 40. I blame the gravity feeder and the flock block for the sudden increase...I have done away with both of those things. The next flock block I buy will be hung. Anyhow....how do I get rid of the mice? My girls are all sleeping on the perch, the babies are on the floor (10 weeks old) and my rooster is sleeping on the oyster shell gravity bin. He's listening to the wall and losing a lot of sleep. I've noticed blood on the walls and with the way he is acting and keeping his distance from everyone (he used to sleep with the big girls on the perch) I think he's listening the darn mice all night and killing them when he can. I need to do something. I'm worried that if the mice run out of crumbs to eat from the leftover banquets...they may attack my "babies" I know the blood on the walls isn't from my birds, I check them all over daily. Any help would be greatly appreciated. Thanks a ton, in advance!
