I had a free range leghorn hen go broody in the laying box. I didn't write down the date so our "21st" day is an estimate. I also once saw another hen in that box a few days later. At about the 14-16 day we moved her and eggs to another pen. It's been in the 30-40s overnight here but we did put a heat lamp in the pen with her (as we do with all the chickens bc they are in three-sided pens at night). I gave up today when I went out and she's off the nest and seems totally disinterested rather than fierce. Out of the 21 eggs she sat on, 2 she pecked open around day 19 to show runny yolks. I candled today (first timer) and 9 were runny. 10 had veins or at least no sloshing. Today is probably day 22-26 or so. What do we do now?
