yes 21 days for all chicken eggs to hatch
Around 3 weeks my bantam chicken is about due to have her eggs hatch and we have let her lay on her eggs for 3 weeks!
21 days
A bantam (mini) chicken egg takes the same amount to time to hatch as a regular egg: about 21 days. The time may be reduced very slightly, but in general it's the same. Of course, if the eggs are infertile, they will never hatch.
21 days after the hen starts to stay on the clutch. A broody hen may take several days to gather enough eggs to brood so do not count the days she is not staying on the nest. There is no difference between the incubation time for a bantam chicken and a standard sized chicken.
Sounds like a late hatch. Most chicks hatch at or around 21 days but there are reasons they may hatch at 23 days. I just had two hatch from a clutch of eggs on day 24 and they are Araucana's.
Actually it takes 21 days. Each chicken takes 21 days to lay an egg, so it takes 21 chickens to get 21 eggs. It also takes 14 chickens to lay 14 eggs in 21 days. Reasoning (mistakenly) that if it takes 21 hens 21 days to lay 21 eggs then it must take 14 hens 14 days to lay 14 eggs, eventually leads to 1 hen laying 1 egg in 1 day. If that were the case, then it would only take that 1 hen to lay 21 eggs in 21 days--but we know it takes 21 hens to lay that amount in 21 days.

If it is many days over 21 days, these eggs are infertile and will not hatch. Though it will initially cause the mother some distress, you must throw the eggs out.
21 days
for 21 or 22 days.
21 days from the date they remain on the eggs. Chickens will take a few days to gather enough eggs to make a brood. Once the hen has decided she has enough eggs she will set and remain on those eggs for 21 days plus a few extra days to hatch late eggs.
