Why hasnt my silkie laid any eggs ?

[connor97]

We are not sure how old she is, but we have had her for about 4 weeks now and she still hasnt laid any eggs. She looks full grown to me but Im no expert, could she still be too young to be laying eggs? Or could something be wrong ?
Here is a picture to get an idea how old she is:

Aw she is cute. Silkies can take longer than other breeds to start laying eggs, and you are right, it can be hard to tell how old she is.
