Ok so I have 7 bantam eggs and 7 barnyard full size mix in the incubator. Today is day 20 i expected I’d at least see some pips today or hear some chirping. I’ve only hatched out once before but that was with a very forgiving and patant bantam hen. The Bantams hatched day 20 and about 8 hrs later the full size eggs hatched. I also seen them move and heard noises. 2 days ago I candled and it looked like the pictures showed they should by that date. Do I have reason to be concerned? Or am I simply a nervous nelly?
