Georgia, my cochin, went broody around 3/7 (that's when we noticed she was staying in the box all day anyway). Originally, she had a blue and a brown egg under her (2). Two days later, another brown egg had shown up so now she had three under her. There was a day of nest box confusion- Georgia returned to a different box while another chicken laid her egg in Georgia's original nest box; once that chicken cleared the nest, I started to move the eggs over to Georgia, but Georgia opted to return to her original box (which was now +1, I thought I'd remove the warm one but all of them were warm. Oops). So Georgia has a mess of eggs under her, all at different stages. My daughter and I candled today and saw veining in many of the brown eggs- one was totally dark and the blue egg was totally dark. These eggs would be 11 days old at least. My questions: what do I do about the different developmental ages? I don't own an incubator. Is it normal to have 11 day old eggs be totally dark? Thanks!
