She
she pecked the next two as well. I agree with you, but within limits. This is a hatchery bird, and as such she is about the epitome of the weakened state you mention. But the eggs aren't hers, so I'm more invested in ten living than in her instincts. I can't really explain what I mean by that... I guess that letting a weakened bird kill the chicks of the improved(ing) line of EE's I'm working on doesn't do anything for strengthening the flock either. I don't trust this particular hen and I'm taking the chicks that she pecks away to at least give them a chance. She's still got four eggs, two of which are pipped. It's gonna be a long night.
The good news is that I have another broody due to hatch Thurs or Fri, so if any of the pecked chicks survive and look healthy I can just give them to her. And she's not a hatchery bird and was herself raised by a broody, so i have no worries about her. Astonishingly enough, the chicks don't look half bad. If they survive the night they're going to need some serious first aid, though.
