More than an average human
It depends on the animal for example if your animal was a hen it would take a shorter time then a duckhhdrgc
NO- the vast majority of the commercial eggs are infertile- the hen never sees a rooster. Fertilization of the egg happend BEFORE the shell membranes and shell are added. Fertilization is not needed to form a shell.
The eggs are fertilised inside the hen, and then laid.
If the hen lays one egg per day it would take 1 year.
16 weeks, usually.
The eggs will remain viable for up to 7 days in cool damp conditions. After that 7 day period the hatch rate will decrease by up to 20% per day
Yes and what you can do to see if there is any eggs under the hen is you can take a stick and lightly lift the hen up and see if there is any eggs under her!
21 days is the incubation time for all chicken breeds.
Not even a minute!
Anywhere from 10 weeks to 10 years though usually on the tenth year you know it is not going to hatch
If you are taking about the hen sitting on eggs then it will make things easy for you and the hen. you will have a better outcome if you move the hen or take the rooster out.
No, the egg is fertilized in the hen before the shell forms around it.
