Breeds with pea combs include Ameraucanas (Easter Eggers), Buckeyes, Brahmas, and Cornish. I think we can rule out Brahma, due to lack of leg feathering and her smaller size. She doesn't look at all Cornish, either. It could be Buckeye, but those are quite rare and tend to be big birds. Then there's also Chanteclers, which are quite rare here but likely more common in your neck of the woods. They have a unique cushion comb, I'm not sure if it is dominant over the single comb like pea is.
The yellow in her hackle (neck) and saddle feathers tells me that genetically she's probably a cross of something red (such as RIR, New Hamp, Buckeye, Partridge Chantecler, or a red Easter Egger) over a Delaware or Columbian-colored bird.
