So its roughly day 18, maybe later though and I candled my hens eggs. There is no light space at all, just a total dark mass, so I am thinking they are closer to hatch that I thought. I didn't see any internal pips or feel any movement though but I didn't hold them long so I could get them back in her nest before she got back from eating and drinking. So I am putting Millie in lockdown and hopefully she gets these babies to hatch. There are 6 good eggs out of 7, I threw one infertile one that never developed away last week. I am so nervous!
