My eggs are on day 21 and they are Wyandotte Bantam eggs. Is this abit too long for Bantam eggs ? I thought they would be hatching at Day 18 or 19 but there is absolutely no pipping or anything. When is the latest time to wait ? Should I discard them at a certain point if there is no sign of life ? This is my first hatch (under a Broody) and I don't know anything. If these eggs are dud ones, should I get some more but would the broody stay on them for an extra 20 days ? She seems more than happy to sit there forever but i wonder if she will simply get bored.
