Very interesting. I dont see RIR in the farms list, Although i can see a lot of strong similarities.. when bought the hatching eggs they had listed breeds below. Mayve you would have better knowledge of what she is based on these breeds?
Bovans Brown, Dekalb White, Lavender Aracuna, Black Copper Maran, Copper Neck Maran, Black Maran, French Maran, Dark Silver Sussex, Speckled Sussex, Welsummer, Bresse Gauloise, Brahma, Cream Legbar
These are the stated breeds of the eggs i could have gotten at that time of purchase. Although everyone on their fb page said welsummer as well as vets. but i have also thought differently to some degree on that too! egg style ect. also eggs medium size too not large like welsummer should have. I know my second hen is a cream legbar with her little crest and blue eggs. but yeah ive always had mixed answers based on the brown one. any input based on breeds listed? again though, thank you very much for your time and input! im still learning as these are my first ever hens. Love this community for advice!
Not entirely sure if im allowed to post links. but here is where i bought them hatching eggs,
