New to hatching eggs

[B1uey]

Hi,
Today I went to a chicken show and I bought 6 fertile Pekin/Cochin eggs.
I have put them under my broody hen.
Do I need to do anything other than wait?
How long does it take for the chicks to hatch?

Thanks in advance.

Hi, in 21 days you should have some chicks. No need to do anything, so much easier with mother hen doing all the work. Good luck.
