To be honest I think this behavior began because I had 2 roosters UNTIL today. The one we rehomed was very aggressive towards the remaining rooster. He ended up staying in the coop when everyone else was in the run eating and hanging out. I think he was so low on the totem pole that he chose to stay in and start a new, bad habit of smashing eggs and having a private meal, alone! I am hopeful that this behavior will end now that the other rooster has been rehomed. He is smashing them IN the NESTING boxes. ANY SUGGESTIONS?
