so tonight is day 23 on my australian spotted (bantam) duck eggs and they are supposed to go into hatching lockdown tomorrow night. i candled them tonight and i am concerned... some of them are almost full of ducky-goodness and some are not. they are all moving and look good otherwise. should i be worried? is it just the position they in? or are they behind in development? they were shipped to me and all put in the bator at the same time if that makes any difference. i have had 0 trouble with temps and humidity. several of the eggs have disrupted air cells but the don't coincide with the different sizes as far as i can tell. 4 are "full" (like 7/8 of the egg) and the rest (7) are like 2/3 - 3/4 "full". thoughts? advice? trying to think of what else might make a difference.... oh i have them in a hovabotor that has the fan in it (don't remember what they called it) i have calibrated my hygrometer and thermometer. i know i am probably overly worried, but i can't help it!
