When do leghorns combs start changing?

When do they start to turn red? I am curious so I now "when" is too early to be a hen and may be a roo! My kiddos are 4 weeks old now and their still yellow/orange but some are a tad darker than others, and some are a tad longer than others.

The next few weeks will give a much better indication.
