Good questions and we've had similar experiences in our first year. Discard the rest of the clutch and put her back in the coop. Let this attempt end, so collect the eggs everyday and take her off the nest if she continues to sit. In a few days she SHOULD stop being broody. Try again next time with only six eggs.I am new to this sort of thing (threads, forums and such) and I signed up so I could ask this detailed question hereforth.
I have a broody hen who started brooding in everyone's favorite nest box. Even though there are 6 other boxes, I would often find two other hens crowding in with and even on top of the broody one. Eggs got shuffled around and mixed, and to my knowledge only one developing egg got pulled into a neighbouring nest box (a sad surprise while making breakfast) I think she managed to keep almost all her original eggs plus a few extra at later start dates. It wasn't until about day 16 for the original clutch that I learnt (from this site) that I could and should move her and the clutch together, which I did successfully at full dark, she was only mildly disoriented and mostly looked relieved the next day to not be pestered by other hens jostling for the prestige nest.
On day 21 I found an almost fully developed chick in the nest I would guess 16-17 days incubation and some crushed shell. Well now it is day 24 and we found her off the nest, looking frantically for her nest (or was suffering from the delusion that she had chicks) and when I led her back to the nest she eagerly settled on them again. The eggs were cool, so assuming them all dead I grabbed 4 to open with which to give my kids a biology lesson. One was fully rotten, but I was surprised to find radically differing stages of development, as far as I could tell different stages of decay among the partially developed eggs. All that windy preamble stated, my questions are thus: will she stay broody until she gets a chick? What are the chances that any of the eggs are alive with less than 3 hours unattended but allowed to cool? How long can a hen's health hold up if she continues to brood past 21 days? Will it be emotionally and hormonally damaging for her if I put her back in the coop away from her nest? And if I put her back in the coop will she recuperate or just start brooding again on the first eggs she finds? This is her first time but she is very determined, today is the first I have seen her off her nest. She is good natured and helps all the other hens to stay calm, an all around good influence on the flock. I am concerned for her health.
