Technically, the eggs should be fertile from 10 days after putting a rooster in with a hen ... however I have had batches from that early not work and tend to wait until 15 days before collecting them for hatching to be on the safe side ... saves you finding out later that you just 'sat' on infertile eggs for three weeks ...

New roosters introduced to the flock need a few days to up to a week or more to familiarize with the flock, the hens will be frightened by a new bird of any gender at first.

The rooster will also need time to get over the fright of changed surroundings.

That depends on the last time the hen layed. I would wait until the second lay after breeding.

What time of year do roosters mate with hens?

Roosters are able to mate anytime of the year, but it's the hens that have to be willing to accept them that counts. Hens begin to lay eggs when the photoperiod (that's how long the sun stays in the sky during a single 24 hour period) gets longer, i.e., spring time. Since the term between copulation and egg development is short, roosters are able to breed hens in the spring time to encourage fertilization of eggs, which give chicks.
