It's confirmed. I have an egg eater. I feed free choice oyster shell, but have been getting a few broken eggs in the last few weeks. I had thought that maybe they were stepped on or broken because so many like a few of the nesting boxes better than the others and there were just too many in there. I collect the 1 or 2 in the morning and then as soon as I get home around 3:30 or 4:00 when I get back home. I can't collect any sooner most days. We just aren't home. We have 30 hens (down from the 65 we started with), all different breeds, and get around 15-20 eggs a day. Yesterday I had 3 eggs that large holes were eaten. Now I know it wasn't an accident. I'm not sure who does it though. I tried golf balls to try to get them to lay in the nesting boxes, but they just kept kicking them out. Guess they thought they were bad eggs. I saw someone posted that chickens will eat all of the eggs that get yolk on them as well. Is is possible that I just didn't clean out the boxes well enough when I found the broken eggs before? We have 5 gallon buckets, for most of our boxes. Can I use bleach? That seems like a bad idea, but what do I know? I just started being a chicken mommy around Easter last year, so I'm still learning. Boy! There's a lot to learn. I'd rather not cull anymore if I don't have to. We are pretty happy with our flock now.
Thanks for any advice!
