I have a young roo and hen that just started laying. I am going to build up my flock right now. They are out of Bamachickens flock. 2 out of the 7 eggs that hatched were rosecomb. I don't believe she has the RIR"s any more.
If you go to Crohio.com and then to the Rhode Island reds forum you will find a thread that has a name or two for very good Rose Comb rhode Island reds.
I dont have the contact information but could probably find them. One is Warren Carlow. I know he is a APA judge and I beleive in the northeast maybe conn. Ther other is D hortsman in Pennsylvania. I dont know either person or flock but a person posted on there for some RC and these names came up
I bought eggs from Dick Horstman who is from PA off of eggbid, they are SQ and he has won at various shows with them. Mine are almost 4 months old but are not laying yet. Great color and type...all like to be picked up and handled, very good dispositions. Would recommend purchasing from Mr. Horstman, I believe his seller name on eggbid is dickschicks.
