Now confirmation hen had twelve at time clutch set. Still at 11. Hatch due late tomorrow into July 4. Hen came off nest early to stretch, defecate, drink, feed, and preen in that order. I let her out so she could get some select greens. Insects super abundant making so very little effort expended for crop filling. She likely did last serious preening for next 2 weeks. Odds are she is talking to embryos now as part of imprinting process. It is very likely she will not come off nest again until July 5 so 3 days of zero feed or water intake coming up. She is in good weight so should have little trouble.
I will be setting up pen for her and chicks to be kept in during night for next month or so. The coop in use does not inspire confidence for chick survival as they come off nest. Chick down coloration will be of particular interest.
