I've been battling egg eaters as well. I swear they all do it. Mostly my Aricaunas...I love them but they're making me nuts. I was getting between 9-12 eggs a day all winter from 13 hens. Now I'm lucky to get 2. We spent hours making roll away nest boxes. ( I found them online for like $65 bucks each...what??!!!) So, here we are day 2...wish me luck. They have always had access to oyster shells, treats, I hang cabbages, squash, melons so they don't get bored. I just ordered chicken saddles as a couple of my "brilliant" Polish girls are getting picked at, and now the egg eating. They are so lucky that they're mine and I love them so much. MEH! Any ideas on how to get them to stop picking at each other's heads? I have a decent sized run (8'x10') right now, way bigger than the ones you see online. I'm going to triple the size this spring so they have more room to run around. Hopefully that helps.
