I have about 23 adult hens. About 4-5 months ago I used to find eggs everywhere in the coops, on the floor, in the nest, and somtimes in the runner, it was great. In the past 3 months if I am lucky I will find like 3 eggs a day sometimes no eggs at all.. Most of the chickens are are younger then 2 years old. They did have lice like 2 months ago but I used a powder and got rid of them and I check them alot and they don't have lice and that's been over 2 months. I feed them 18% layer pellets all the time and it's the same result.. I buy so many eggs at the supermarket now but I second guess why I have hens when 23 hens when they only lay 1-3 eggs. I spend my cash on there food when they don't return the favor. I do have a rooster in the cage that is mean to the hens and bites them somtimes maybe he is the problem? I hate him but that my dads rooster lol..
