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.
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.
