When we came back from the fair this year we took out all of the roosters that were with the egg layers and now they are not laying any eggs at all.before we had 3 roosters with about 20 hens but no roosters with them anymore.I know you don't need a rooster for them to lay eggs but do you think they stopped because there is not a rooster with them anymore? the hens are anywhere from 6 months old to 3 years old.or do i have something getting in and eating the eggs?
