It takes exactly 8 weeks for a emu egg to hatch, & they should be incubated at a steady temp of 96-97 degrees. If incubated at a higher temperature, the chicks will have trouble getting out of the egg. This is because the egg shell hardens.
It tacks around about 21 days for a chicken to hatch
They lay about 3-4 eggs.
It is unlikely you will get any to hatch. 7 to 10 days is about maximum storage pre-incubation. After 10 days, even in ideal storage, the hatch success rate is reduced by about 10% per day.
21 days is the incubation time for all chicken breeds.
ALL breeds of chickens have the same incubation period. 21-28 days are how long mine usually take.
Tasmanian devils do not have an incubation period. The term "incubation" relates to how long an egg takes to hatch, and Tasmanian devils do not lay eggs. The gestation period of the Tasmanian devil is between 18 and 21 days.
Shortest incubation - around 11 days for quite a few small passerines. Longest incubation - no simple answer as some birds can stop incubation from time to time and the egg(s) will still hatch, but over 80 days has been recorded for kiwis and albatrosses, including periods of desertion. Emperor penguins continuously incubate their eggs and incubation takes 9-10 weeks.
The incubation period for bird eggs varies depending on the species, ranging from as short as 11-13 days for some small songbirds to as long as 80 days for large birds like ostriches. Generally, most bird species have an incubation period of around 14-30 days.
It can take up to twenty one days for a chick to hatch out of the egg. In incubation, it may take up to 24 hours for a chick to hatch out of the egg.
Cactus Wrens - incubation 16 days - another 19 to 23 days for fledgling. Both parents feed the babies.
In the case of eggs, size does not matter. A fertilized peewee egg when subject to proper incubation conditions will take 21 days to hatch the same time it takes a jumbo egg to hatch under the same conditions.
I believe it take 21 days for a egg to hatch It depends entirely upon the species. Insect eggs may take a matter of days to hatch. Birds' eggs may take around three weeks. The kiwi's egg has an incubation period of 70-80 days.
