Sorry if this topic already exists, I couldn't find anything in the search. I'm fairly certain all my hens are more than old enough to start laying eggs. At night I put them in their pen, but at day they are free to wander the yard. Every morning I check their pen for eggs and not a single egg yet. Are they laying them during the day? I scour the yard every day for eggs as well, maybe where I am just not finding them?
