i candled my eggs again tonight and still i think 1 of my eggs has quit but don't really want to toss it yet just in case. the other 5 are doing fine, very active and due to hatch the 19th or 20th but i noticed that some of the chicks do not fill the egg as much as the others. there are 2 eggs that are almost completely dark with chick (other than the air sac of course) and don't move as much as the other 3 that don't look as "full". is this normal? and why would some of the chicks be bigger than the others when they were set at the same time? the eggs come from a standard size RIR roo and OEGB hen if that helps any.
