my hen went broody and I think she stole some of the other hens Eggs along the way and may have a few chicks that are developing behind others. I now have them marked and candled them today. Question is, is it ok for some to hatch and then the others to need a few more days? This was not planned and so we didn't get off to good start as far as marking eggs and even knowing when she started to sit. I have a general idea but not exact day.
