My chickens are in a converted stall with 2x4 horse wire on the top. Magpies have recently discovered the tasty eggs and will raid the boxes almost as fast as the eggs are laid. Short of putting up all new wire (a new coop and run is in the works and the current one will be a grow out pen only) anyone have some tips on discouraging these pests? I do have 2 nesting pairs of birds but their nests are too high to knock out of the trees. There is some justice however. An owl recently moved in this past weekend and cleaned out one nest of young birds for me.
