no chick here has been harmed by another bird here
This is where we might have had slightly different experiences, although I can’t be sure, and probably will never know, unless the same happens this year.
You might remember the trouble Galadriel (the Brahma cross) hen had last year, with one chick hatching with (what was probably) their intestines outside their body, and passing shortly after.
While I can’t know for sure, three are the most probable explanations as to why that happened: The chick could have been that way on its own, through some kind of developmental or genetic issue. As a first time broody, and still a pullet (at the time), mum was too overzealous and assisted the chick in hatching too early, causing the problem. What I consider to be most likely, however, given the blood on and around the area where the organs were protruding, as well as the fact that I found the chick below the nest, with a panicked mum still sitting, is that another group member interfered. At the top of my list is the head hen, who has attacked unclaimed (brooder) chicks before, which I can excuse. She was near the nest, presumably to wanting to get in and Galadriel was not one to stand her ground against higher-ranking older birds, at the time.
I did a lot of things wrong during that hatch, letting Galadriel sit in the favourite nest box as a lower-ranking member, not blocking off the nest during the hatching process, etc. Most of what happened was my fault. Still, I wonder if the other hen(s) really did mess with the chick, or if the failure of the hatch is completely on me.
That being said, both successful broody hatches of last summer, curtesy of the the bantam group, did monitored ranging time, and none of the chicks got attacked. The mothers were regularly targeted by the members of the Tsouloufati group, but never the chicks. So there’s definitely more to it
