Looks like an Old English Game bantam. They are small bantams, which is why she stopped growing a long time ago. Her variety is probably white, as I don't see any red or orange in the hackles, which would indicate that it was a Red Pyle. And, I agree, she will likely be laying in a short time (based off of the color of the comb and wattles). Pretty girl! OEGB are nice little birds.
Looks like an Old English Game Bantam (OEGB) or OEGB cross pullet. OEGBs have four toes, not five, so I think a mix is more likely. She's cute! The small size is normal for OEGBs; they're one of the smallest bantam breeds.
