Hmmmmm! Just a thought! Let me run this idea with you all and see what your inputs and comments would be! For those of you (and me) wanted to do some preventive measures of this terrible year of mites, lices and all sorts of bugs in our laying girls. Get one hard plastic easter egg, put some holes in it, open the half and pour Sevin dust in it, tightened back up and put it in the nesting box. Voila! Self dusting when the hens come in to lay, shifted the egg around that the dust will be underneath her chest and legs (good for leg mites too!). Would this work????????? Try this on your birds and let me know if it works! Another one would be the cheesecloth bag similar to the weight lifter's dust bags when they dust their hands before coming on to the stage to lift those weights. Not sure where to get those kind of bags but it would make a nice comfy blanket for them to sit on. One disadvantage would be if they get to be so comfy, they might end up sleeping in the nest boxes.
