Runner age?

[anniele27]

We just got runners from the farm store yesterday and I'm curious if anyone has any guesses at what age they may be!

Also because they are yellow they'll most likely turn white with brown right?

These were my runners day 8 - not the best, but maybe you can get an idea.

Ours about 7 inches tall and yours look about that so I'm estimating mine are probably around that age! Thank you!
