Today is hatch day for my 8 Silkie eggs. When I moved them to the hatcher and candled them on day 18 everyone looked fine and there was definite embryo movement in each egg. I monitored the egg weight throughout and the used that to regulate humidity and on day 18 they had all lost approx. 10-12% of their starting weight as they should have. This is only my 4th hatch but on each of the others, I had a few pip a day early each time and then almost all hatched on the day they were supposed to. I know it is still early, but based on my 3 prior experiences I am starting to worry that something is wrong since there is NO activity yet. What do you think?
