Candling means to hold the egg up to a light and see if there is a chicken in the egg and what stage the chicken is in its growing process. It isn't essential for the chicken to hatch, you can just do it if you want to make sure there is a chicken in the egg.
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.
Chickens do not need to mate in order to lay eggs. Hens will lay eggs regardless of whether or not they have mated with a rooster. However, if a hen does mate with a rooster, the eggs can be fertilized and potentially hatch into chicks.
Generally speaking, no. Male fowl do not lay eggs. However, there is a mythological creature known as a cockatrice that is said to hatch from an egg laid by a cock and incubated by a toad(or a snake, depending on the story).
The rate in a hatch is normally about 50/50 but small fluctuations in temperature during incubation with higher than normal temperature (100.2F) will result in a larger ratio of male to female hatch.
Wild ducks certainly do and many farms have ducks that set eggs each spring but there are hatcheries that incubate duck eggs just as most chickens are produced in a hatchery.
Many things can walk when they hatch including chickens.
Use eggs.
Chickens only lay eggs. Baby chickens (chicks) hatch from those eggs and grow up. If the eggs are not fertilized, however, then they will not hatch. Those are the ones that are eaten.
sometimes matters though.
No, there is not.
chickens hatch on the 21st day after the 24th day you should give up.
well they can after maybe an hour
Yes they can. This is how it has always been done!
People use chickens to lay (eggs), hatch chicks, raise for meat and to show them off.
The sentence contains one noun (chickens) and one pronoun (they).
No they dont, they lay eggs and have to hatch them the same as chickens do.
Only if you want to hatch chicks. Then, no you don't have to.
