How can you tell how old a hen is?

I bought 5 New hampshires recently and was wondering if there are any ways for telling how old they are. This is mainly because I want to know when they're going to produce eggs!

You might try posting pictures in the breed and gender forum, especially if you think you might have a roo. You can guess a general age by size and how well they are feathered and developed. In general though, if they are fully feathered and about adult size they are probably four months or better and a couple of weeks or month or so before pullets start to lay the combs and wattles will grow and get red.
