How old is my silkie really?

[smlinn17]

The cockerel on the left is eight to nine months old. I was told that the pullet on the right was born in December, making her around four months old. I'm not sure if that is true? Thoughts? Thanks.

Well, they look about the same age to me, although the pullet looks a little bit younger.
I'd say that the pullet is a little bit older than what you were told, but only by a little bit. Maybe 5-6 months?
You could also try looking up the different age-stages of Silkies on google?

I hope this helps!
