This is why I dont have chickens now.... I lost everything about four years ago to Coyote attack... catastrauphic failure on my part. Then I lost my goats to mountain lion.
No my chicken coop will be made of 12.5 gauge aviary wire.... spaced 1/2 x 3 inches.
Anything that can get through that will be edible....
So sorry about that.
That's good its better secured now though.
