Hope you are doing okay... loosing chicks is horrible

they are such helpless creatures, it's upsetting to see something so innocent die of situations or of its control. And hmm, I'll bear that in mind, though we have tiny houses here in England haha. I don't know anyone on this side of the pond that has a basement honestly.
And yes, I suppose they are gradually getting bigger, they will lay a smaller one, then a few big ones. They themselves were hatched around April/may this year, so I suppose they still need time to get to their optimal egg size. The chicks seem to be huge inside the egg, with barely any room at hatch. There was most certainly no room for most of them to move their head to pip internally or externally. It still kills me that the one that did pip externally died suddenly after one day of running around like it was healthy. This makes me wonder if the parents potentially have an illness that doesn't effect them, but could effect chicks?
