I was given 10+ birds from a woman who claimed she was getting a few daily. Together I now have 25 hens. Not a single egg. Nothing. Nada. Zilch. They now have unlimited access to feed. They are not being harassed by predators. Coop is enclosed as in the run. I feed a 16-18 percent layer feed with corn. I have young hens that should start laying anytime now. Red wattles and such. No eggs. They sleep in my nesting boxes and make a mess. They kick the fake eggs out of the coop too. What should I do? Close the coop during the day and force them to use the outdoor roll out nesting box and not allow them in until dusk?
