I have had chickens over many years in several states, and wish to begin anew, with a few fancy bantams and "external..pop-out nest boxes" on the east side of the coop. I have never had any experience with fancy-dancy external nest boxes. I see that some nest boxes open from the TOP, such as "raising the roof" of the nest box protrusion. Other boxes have a "drop front", whereby the front wall panel is hinged to fall down. Looks like the "front-drop-door" would be easier to clean, but the "raise-roof" design might be more varmint proof? Should I "drop my drawers", or "blow my roof"? Does one method work better, for not panicking hens? Other reasons for choosing one style over another? We are still in the designing phase, but time in narrowing. Any opinions? Thanks,...call me confused.
