It has never happened to me but it is not uncommon! Was your broody a first timer! She may have by accident squished the chick.![]()
It seems to me it is common enough in nature for at least one to die. The same thing happened to me with both my broodies. One died from getting out of the nest and getting stuck, the other one didn't absorb it's yolk and didn't finish hatching. Then of course there are the bad eggs that don't hatch. It's all just luck of the draw, and since with a broody there are so many variables it's hard to tell. I think, in my limited experience, broodies actually have better hatch rates than those from an incubator! Not to mention the babies seem tougher from the get go. Don't best yourself up over it, it's all part of the experience of hatching chicks unfortunately.
Thanks guys. Yeah this was her. First time and my first time with a broody. I have another chicken wanting to go broody but we dont have room for more chicks right now...
