I have a question for those more experienced than me with hatching eggs under a broody... this is really long, sorry! I've only hatched eggs once before - two years ago, I let one of my Polish hens keep 6 eggs she hid behind a nest box. Unfortunately, my frequently-broody Buff Orpington decided she wanted to sit on them as well, and they somehow managed to break all but 2 of them in the first week or so. Both eggs pipped, but one chick never made it out of the shell. I have small pen inside my larger chicken run that I use for introducing new flock members, so I moved the sole survivor and Mama Dhu (the black Polish) into it and she successfully raised him to maturity. So... A month ago, we had a freak snow storm that started out very wet, then turned to rain. A huge clump of the resulting slush slid off the barn roof, then froze hard in front of the access door to the chicken house, so I didn't collect eggs for a few days. So of course when it got warm enough to clear the door, I found Mama Buff sitting on 23 eggs. (She's a big fat hen, and the rest of the flock lays relatively small eggs.) I took away most of them, but left her 8, which I marked. She's super friendly and doesn't peck or bite even when she's sitting, so every couple of days I lifted her off & took away any unmarked ones that showed up. I didn't candle the eggs since I don't routinely do it & didn't have a setup for it. A week and a half ago, I found her sitting in the wrong nest box, on eggs that had been laid earlier the same day. The eggs she was supposed to be sitting on were cold, but it was a warm day. I moved her back to the correct nest & she stayed there. Two days later, I found she had 9 eggs but 2 of them were unmarked... and 1 of them had yolk and blood on it. I searched the nest and found the partial remains of a chick; clearly somebody else had managed to break its egg in the process of laying her own. At that point, I picked up the nest box with hen, remaining 7 eggs, and all, and moved it into the baby pen. She was unperturbed and went on sitting. Based on when I first found her sitting on the eggs, 21 days would have been this past Thursday... nothing happened. I decided to wait until Saturday (yesterday), then remove the eggs. Yesterday morning, I went in to take away the eggs, and the first one I picked up PEEPED at me. None of the others seemed to be making a sound, but I left them all alone. Yesterday evening, that one egg pipped, and a couple of hours ago I found a still-damp, very small baby under Mama B. So, at the end of this much too long story, the question is - should I leave the other eggs for another 24 hours or so, or just take them away now?
