I started with 30 eggs, 10 were non developing and those I got rid of on day 7 1 had an obvious blood ring and I cracked it and there was maybe 2 or 3 days development. so that left me with 20 today I candled the remaining 19 10 I can see really vigorous movement from the embryo. 3 were blood rings (haven't opened them yet, waiting for my son to get home to see) and the other six I can see embryos but no obvious movement so i'm left with 16 in the incubator I want to know what you think of the size of the aircells? I think maybe they are a bit big? the humidity has been around 40% should I work to get it up to 50? or do they look to be the right size to you ?
