I came home last night to get eggs, expecting about 18, to fine 0. I know there were a few yesterday already, b/c when I went out to let the chickens out to range and feed/water them, there were about 5 in boxes. I have a guard dog who I don't think can fit in the chicken door, and 2 cats. The chickens were NOT upset, nothing looked amiss at all. There is NO evidence, not a shred. I am certain no humans would take the eggs (the dog, for one, would scare them off, and for two, its just not that well traveled around here). My only guess at this point is maybe a gopher (but all 18 eggs?), or maybe the cats (again all 18?), or almost impossibly, the dog? Any thoughts?
