I have 7 hens that just turned a year old back in March.....Up until about 2 weeks ago they were laying like clockwork...I was getting between 4 and 7 eggs per day.....Now i'm lucky to get 3 a day and some day's just 1.....I have 1 leghorn that lay's white eggs and she hasn't laid in about 4 days.....I check and didn't see any bugs.....I sprayed the chickens and coop and run with permethrin just in case.....Is this just a cycle or am I perhaps missing something....I have not changed their diet and I know I don't have any egg eaters (i've been checking for an egg mess and have not found any)
