I had a little bantam OEG hen sitting on eggs in her run. She made a secret nest outside of her nest box. I had been keeping an eye on her. She is alone besides her devoted roo. He always takes very good care of her. Anyway, this morning I checked and she was off the nest looking very distraut. There were shells around that look like after a chick hatches (top zipped open, but still attached). I can't figure out what got the chicks. The run is cat proof, dog proof - I've had racoons pull large chickens heads off through the run, but none have ever gotten into it. We've had snakes before too (they were, er, eliminated), but they always ate the eggs. I can't imagine one waiting around for the chicks to hatch unless it was just good timing on their part. I am just sick about this. We had just hatched some of her eggs in the incubator - they are one week old, when we found she was brooding. I wish I had moved her to a safer place, but I was afraid she would freak out and stop brooding. Any ideas? There were no chick parts left behind, just the shells - no blood, feathers, etc. Thanks everyone.
