We have 8 hens. They are just about 14 months old. Until just 2 months ago just about all of them were laying daily. Over the past 2 months however we are down to just 2 eggs / day and not from the same hens but it varies. We have 4 silkies, 2 americaunas and silver laced wyandotte. We live in Florida. Nothing has changed about their location, feed, or otherwise. Does anyone have any thoughts on reason for this or suggestion on something we can do?
