I had 4 hens that decided to nest in one box. 3 weeks ago, the eggs started hatching. One of my bantam cochins jumped out of the box and started caring for the 6 new baby chicks, leaving the 3 other hens with the eggs. I found 4 scalped and dead over the next week but I thought they were being born that way and kicked out of the box, cause mom was doing great with the other 6. More eggs hatched over the weekend and it seems like one of the 3 hens is scalping the babies and kicking them out of the box. I kept going out and finding new babies shivering under the box with their heads all bloody. Because I thought they were being born that way I left a few perfect looking chicks out there only to come back out to (thankfully just a little) a bloody little head.I'm raising them all inside now, I can't believe some are surviving! This must happen in just minutes! I haven't seen anyone picking at them and I'm out there constantly.
