I just don't know what else to do. My girls have really slacked off on their egg laying. I've done everything I can think of. I found one hen infested with mites. A week ago I dusted her, the rest of the flock, the coop, changed all the nest boxes to fresh bedding, cleaned the run and coop and dusted their favorite dusting spot. I have wormed them, thinking that perhaps they needed it, even though I have not seen evidence of worms. I add ACV (apple cider vinegar) to their water, so I didn't expect worms to be a problem. No one is molting. There's no excess feathers laying around. I stopped giving them treats every day, now it's once a week, and then it's a small amount of treats. Up until the past week, heat has not been an issue. Their routine has not changed. The coop is clean and fresh. There is no more snake problem nor any other predator that I can see evidence of. We did cull 7 extra roos yesterday and sent them for a visit to freezer camp, so maybe that scared the ladies into going back to their regularly scheduled laying...we'll see. My last idea is to split off the flock into two flocks-one with the established layers and the other with my pullets that hatched this year + the roo I hatched this year. Does any one have any more ideas? I don't sell my eggs, I give them to friends and neighbors, but I hate having to telle very one that I don't have any.
