The neighbor brings his grandkids to feed the goats and chickens, they were feeding them corn, and I was only getting 9-10 eggs from 15 hens. so I cut out the corn and they started feeding them regular laying pellets and production went up to 13-14 eggs a day. Guess they were filling up on corn and not the good stuff. now I only have 10 hens and was getting 8-9 eggs but last Friday I only got 4 and Saturday 5 Sunday 4. Thanks to you all for your comments and advice. I will remain diligent in my pursuit of the chicken murderer.
