My 2 hens are 3 months old and have been laying an egg a day since they turned 8 weeks. The past few weeks they sometimes go 1-3 days without laying any eggs. I know they can be tempermental, but we haven't changed anything. A few times in the past few weeks we have found smaller eggs with NO speckling--almost pure white. What is that? They are still on chicken chick feed (I used to add protein but stopped about a month ago), and get bugs they peck (mostly roly polies, earwigs and spiders), along with meal worms as treats each day (yeah, they're spoiled!). Any ideas on why the slowdown in laying and why the smaller, white eggs?
