I've got a broody hen - She has been a good sitter so far. Last night I fenced off a quarter of the coop to allow the chicks protection from the rest of the flock. I expect them about Monday. Anyway - when I got home this afternoon I found the hen had flown the coop & couldn't get back in so she decided to sit on someone elses eggs. The eggs were cold to the touch. I put them in the bator - but don't hold out any hope. Should I wait until Monday/Tuesday or open them now?
