Twenty chicks have been hatched so far, with only one loss in the first day. Two hens hatched six chicks each, and the other two hatched four each. The last hen to hatch was the one that lost a chick. There could have been something wrong with it, or she could have stomped on it. I saw her stomp another chick clumsily and she is a big girl, a Buff Brahma purchased last year at the local feed store as a week old chick.
It seems like a different hen went broody about every three weeks or so, so each family of chicks is a different size, from teensy fluffballs to almost full grown.
