Open soffit where roof hits the upper wall plate, doors that flex at top or bottom even when locked or latched, if raised off the ground holes in flooring, holes in walls, holes in roof, poorly latched chicken door, and predators in the coop when you closed it. Predators in the coop happens more...
Hi :)
I'm a new guy here :) Raised farming ranching in Montana/Wyoming now pastoring a country church in Central Michigan :) I have raised poultry for years off and on. Everything from a dozen to a hundred or so... Chickens, Ducks, Geese, etc.
But I find I can always learn more from others...
