The length of the incubation for the bullfrog is about 4 days or less.

The term "gestation length" refers to mammals. Pheasants are birds, not mammals. So the number you are looking for is more commonly referred to as "time to hatching" or perhaps "incubation length."
Gestation is the term applied to animals that give birth to live young. The time that it takes an egg to hatch is called "Incubation". According to http://www.carolinaraptorcenter.org/b_eagle.php, the incubation period for bald eagles is 34 to 37 days.

Bluebirds do not have a gestation period, which refers to the length of a pregnancy. As birds lay eggs, they do not have gestation, but an incubation period, which refers to the length of time an egg is kept warm until it hatches. The incubation period for bluebird eggs is 12-14 days, but incubation may not start until a week after the first egg is laid, in which case the period can extend to 19 days.
The period between fertilization and birth is called pregnancy or the gestation period. For humans, gestation lasts about nine months. and isn't it cute. SO ADORABLE
