They are a mix of RIR, SLW, and some other big white chicken with feathered legs
There are also some light brahma standard hens in the mix. All the parents are pure breeds, but they are all together. So some could be pure, and some mixed. The majority of the hens are RIR, with 3 RIR roos, 3 SLW roos, and 2 of the other roos. Let me know if you are interested.
<edit> We get at least 25 eggs a day from these birds, so they will definitely be fresh. There is about a 5:1 ratio, so they should all be fertile.
