You know i've been thinking about it and they were not that shrink wrapped until after day 21. On day 22 I candled and the air cell was normal. By day 24 the air cell was 50% of the egg. Humidity at 75% how could they have lost so much moisture?
That's what i said about mine too. When I candled on day 23, they were still fluid, so maybe its just the extra time length, plus the chick grows a little more every day.
