What Neal said. Jennys are usually the last to breed and may not try again after losing a nest. Adult hens (2 yoa or better) will start earlier and will try multiple times using up available body resources, I think studies have shown up to 5 or 6 times. A little tidbit... Gobbler sperm is viable up to 30 days in the hen. So a hen may not need a gobbler after losing a nest. Conjecture, not enough studies yet. So what you saw is not out of the norm, and could be a combination of things.
