Help! Something is burrowing holes in my chicken pen
Agree with hardware cloth....sounds like rats...which are a very persistent menace and will eat you out of house and home, chicken feed wise, especially during winter when there is less forage.
And if they can't go under, they will go over, through or between.
You may consider setting some rat traps. Place under a milk crate so the chickens can't get into them. I've had smaller game birds actually killed by a rat trap. Larger breed injured.
Stay on top of it...the more they know you've got goodies, the more come, and produce more, that creates this incredible population explosion that is hard to get under control if you get behind it.
