It depends on what kind of bird so I can not give you a strait answer.
21 days from the day they are set into the incubator (not from the day they are laid).
A broody hen will collect a clutch for up to one week before setting on the eggs and they will all hatch within about 12 hours of each other.
Depends on what kind of egg. An average time for a chicken egg at optimal temperature is 21 days. Every animal is different. Muscovy is a type of duck but the incubation time is longer than most other types of ducks.
Duck, Thurkey, and Goose eggs take about 28-30 days to hatch, except for muscovie ducks which take about 35 days. Guinea hen eggs take 26-28 days. Chicken eggs take about 21 days. A incubator will have instructions on it about the tempature.
Incubation Times for eggs
Poultry incubation duration can vary from species to species but is generally about 3 weeks (21 days).
Chickens......21 days
Ducks (most).....28 days
Muskovy ducks..35 to 37 days
Turkeys.......28 days
Goose.........28 to 34 days
Guinea Hen.....28 days
Pheasant........23 to 28 days
Peafowl .........28 to 30 days
Quail...............23 to 24 days (some exceptions)
Grouse............25 days
Pigeon............17 days
Partridge........ 23 days
if the right settings are set to the incubator it should 21 days
Depends on the kind of animal that laid it.
69 days
21 days.
They most likely will not hatch at all.
about 21 days
An incubator is used to hatch fertile eggs artificially. Nothing will hatch from an unfertilised egg.
If you can hatch a regular egg in there then you can hatch an ostrich egg.
Invest in an incubator.
It depends. Did stay out in the cold for too long? If it did it will hatch but maybe become sick or die in the egg
That egg will not hatch. Take it out. Bacteria will grow in it and also the moisture has all been lost. You do not want it to affect your other eggs that are in the incubator.
it happens mostly at day time because its warm blooded and they sleep at night
it has to be fertilized, and you can stick it in an incubator.
It takes three weeks or 21 days to hatch a fertilized chicken egg. Temperature and humidity must be maintained constantly. Two weeks is not long enough and incubation cannot be hurried.
An incubator is the best way but a simple light bulb incubator is sufficient to hatch eggs.
The chicken egg will likely hatch first. Quail eggs hatch in 21 to 23 days. Chicken eggs hatch in 21.
