Hello- I have like 23 chickens different breeds and like 4 roosters. They stopped laying eggs about a month ago, they do not seem sick, they are not loosing feathers and they are not hiding their eggs. we killed a snake like 3 months ago but we have not seen anymore. We haven't change their feed and they have over 2 acres to roam around freely... I am at lost. Anyone have a suggestion? or anything that could get me eggs! I dont like grocery store eggs!
