I have an Easter Egger hen that went missing for a month---I figured coyotes had gotten her but she was in my haybarn hiding out. She hatched 16 chicks. Found her the day they had started to hatch out. I moved her to an old empty water tank with lots of hay, feed and water. About ten days into raising her family she brutally started to attack some of her babies. She injured one bad enough that it died. I then took her and put her with the flock and got the babies a heat bulb. Everyone is doing fine now. What my question is---is why did the hen turn on her own babies??? Is this common? Any ideas or suggestions or has anyone had this happen with their hen and new chicks??? I'm curious as I have always taken the hatched babies and put them under a heat lamp and raised them without "mama". I just thought since she was such a good mama I would let her raise them herself. Are Easter Eggers prone to being aggressive???
