May sound goofy but check for rodents in the coop at night. I had a pair of rats move into the coop and they were running all over the nest boxes and roosts at night. It cut my egg count way back. I no longer have food in the coop, I moved it out into the covered run. Egg count was back to normal within a week of catching the rats.ok ive looked in the other forums and have not found much helkp i have four hens capable of laying and all were one went on strike for two weeks now and the other 3 just a few days all different breeds and one is a month older then the rest i dont get it i thought it may be there feed i switched it to the omega3 purina (which they have been eating for over a month) and at first they were eating then i noticed the last few days they have not they do have a pretty big run and i do let them free range as much as possible now i went and bought there orginal feed which i know there eating tested that but i wouldnt think it would take that long to have an effect like that idk my BRLW is 8months and my 2 EEs and golden sexlink are 7 months ANYBODY HAVE ANY IDEAS all input is appreciateted
