Hens that don't lay

[wjallen05]

I have two (true) Ameraucana hens that I hatched out last February. I hatched out some Silkies at the same time and they have been laying every day for months (except recently since they have both gone broody). Neither of the Ameraucanas has laid a single egg yet. I am getting tired of waiting. ALL my other hens and even the ones from my June hatch are laying great. I have three Easter Eggers that are laying- but these dang Ameraucanas just WON'T lay. Why?!?!?!
(btw they are fed layer crumbles, fresh grass, fruits and vegetables)

they are late bloomers. mine always start laying late, if their healthy . other wise check for parasites
