Over the last week I've been letting the girls do "clean-up crew" in my veggie garden. They were spending a few hours free ranging every day before this, but now they're out there all day in the garden. I've been putting piles of compost in for them to knock down and they are having a great time. So now the problem: I've only gotten 5 eggs in the last three days despite usually getting 9. I thought it was no big deal since several are molting. Today however I had one egg with big smears of blood (no obvious injuries on hen) and two eggs that only had partial shells. Are they overdoing it out there? Could the partially broken down compost be hurting them?
