We have some friends who have a really well-built chicken coop. Sometimes we help them with the birds when they are out of town and bring back eggs.
A while back they had a stump in front of the house with a family of foxes living in it and they pointed a game camera at it.
Night after night they got footage of the fox mama bringing back other people's chickens to feed to her kits.
The moral is, I think, that the well-built chicken coop is a good investment.
I built a terrible chicken coop. Truly awful, cobbled together out of whatever junk I could find in a hurry in the dark, as my wife had a pair of chickens foisted upon her on the way home that evening.
It was enclosed. The largest aperture was 20mm. Even enclosed on the floor.
Anyway. Anyone who keeps chickens already knows what I fucked up there.
2am. Almighty screaming from outdoors. A chicken has managed to squeeze its head through the grille, and into the mouth of a fox. Everything then rapidly devolved into a surprisingly large amount of blood, where I’ll just elide the details as they’re kinda grim.
Anyway, the bodies went in the pot the next day, and I now know why chicken wire is specifically called chicken wire.
