Yes those chickies will slurp them down. I put them where they cannot get to them. I use a feed bag with poop in it as I kinda know when they should be coming and put them in there. They hatch and do their thing. Sometimes when Arbico sends me extras I will bury it in the compost pile where birds or ground squirrels can't get to them. You can do so many things to keep them out of chicken's beak territory. I'm so glad I put out the extra money. Even though we bloomed a giant crop after the end of July rains when I got my eliminators they mostly took care of them. I have 20 girls and a giant compost pile, plus I live across the road from cotton crops this year, alfalfa last year and 4 horses just a short distance away - maybe about 3/4 acres (I have been known to go and bury the eliminators in their poop area!). Arbico has a solar fly system that I would like to get too although I haven't done enough research yet.Do you have any problems with the chickens eating them? Especially when they're still pupae?
