Sorry to hear about your hatch
@Katejc, I’m sure knowing you tried helps, and I would have done the same.
I think maybe it’s a bit different when you only have a small backyard flock that are destined to be pets. We recently lost a pullet who was 11 months and seemingly happy and healthy. The only resolve I have, is maybe there was an underlying issue as she had pasty butt as a chick, and her navel was exposed - although we didn’t hatch her.
All part of the circle of life I guess, but hope it wasn’t too hard to find.
