Chiken eggs?

Question

Ok, so my freind bought me a egg today( I asked for one), the chicked laid it last night, and he took it & kept it in a incubator & then bought the egg to school for me, So :

1. does this mean that the egg wont hatch even if I keep it heated 4 the 3 weeks required, because I been at school for the past 12-15 hours(long bus ride) So the egg wasnt really warm, the shell was a little cold

2.He bought me 2 eggs, but during school, I accdentely cracked one of them, but its a tinyyy crack, so did i damage my future chick?

3.So though my chick wasnt warm all today (cusi was at school), like about 15 hours, did I damage it anyway?

4. So now I have the two eggs, & like a heated lamp next to them, What next?

5. OO, & if I keep them togheer( the eggs) will I damage them?

6. How do i know if my egg will hacth? I dont want to leave my lamp on for 3 weeks & realze that the egg was not fertile.

THANK U GUYS!

Answer 1

Ask your friend if he runs a cockerel with his hens.  If the egg isn't fertilized, nothing will make it hatch.

Answer 2

chicken eggs have to be fertilized by a rooster just before they get laid ,most eggs you buy from a store for eating ,are laid in cages with out a rooster and are infertile (no chick)

if it is a farmyard egg and there was a rooster you need an incubater that has a constant temperature and that rotates the eggs
