More than likely she is setting, she will not get of her nest very often, and only a brief time, usually after setting for a while one of my hens comes in and does a peahen cry, like she is on high alert, if I hear her I go out and call her in and give her food, than I wait for her to leave and see where her nest is, one year it was really late in October and I knew those eggs could not be good, she had been sitting forever, me and my grandsons tried to remove her, quite a fight, when we got close she was so tight in her nest and not any movement, she would not move, just kept pecking at us. Finally I got her and held her tight, boys got the eggs x6, and I checked all were bad. Took them away and right back on the nest she went. She sat another week on the nest with no eggs, before she came back to be with the other peacocks. She had hatched in June x 5 babies that I let her have, then July I sold the young ones and thats why she thought I need more babies, by then my males had dropped the tail feathers, and probaly did not mate with her, so she went on to lay eggs and sit, poor peahen....she is 7 years old and hatches great peachicks, but my place can not support to many, so I sell them, onless I need replacements. Just keep your eyes and ears open........
