I just opened the unhatched eggs this morning from the weekend and 6 out of 7 had developed chicks in them but never hatched, I cant think of why this would have happened I candled on day 18 before I locked them down, I wondering if they could have drown in there shells or something
I dry incubated them, the humidity was averaged around 27% and then on lock down averaged around 67-70% any idea as to why this could happen I was disappointed as I though they may have been under developed but to see them with beaks and feet is even more disappointing x
