Bird eggs will only develop at a temperature close to the body temperature of the parent bird. Thus, a parent bird usually incubates the eggs by sitting on them to keep them warm.
The pronoun that takes the place of the noun bird is itas a singular and they or them as the plural.The bird sat on my window sill for a long time, as if it wanted to tell me something.If the gender of the bird is known, then the pronouns he/him or she/her can be used; they or them is also used for the plural.When the bird flew from the nest I could see that she had two eggs.
That bird's eggs. The possessive noun is in bold.
6-8 weeks
Noramally, is pretty difficult to determine wether the bird will lay eggs or not. But keep in mind if it's one bird, it wont hatch. It takes a female and male. Females can lay eggs on their own but it wont be fertilized. You could probably tell if the bird goes inside a nesting box (if she has one) often.
