Not really. The only birds I really concentrate on are birds first to be pleasing to my eye as I interpret the SOP's, but some clearly aren't going to be shown. I figure by around a year old they are in their prime. I keep track of the birds I'm most interested in. I keep the best.
The Rhode Island White is a moderately-sized, completely white bird with the males weighing 8 1/2 lbs. and females 6 1/2 lbs. They have long, broad, and deep bodies which are carried horizontally, giving them an oblong and brick-like appearance overall. Their breasts are deep, full, and well rounded. Their heads are fairly deep and are inclined to be flat on top rather than round. Though some single combed offspring do occasionally occur, the breed is has been standardized only with a rose shaped comb. Productive strains of this breed typically lay in the 240-250 eggs per year range. They are reputed to be splendid meat fowl and excellent layers of winter eggs. Rhode Island Whites are pleasant, easy going chickens and would make an enjoyable addition to any family farm. Today, the Rhode Island White chicken continues to have its followers.
I have been breeding Rhode Island Whites for several years. This past year for the first time, I had some single comb chicks hatch from my Rose Combs. I'm going to do an experiment. I do have a few single comb females right now in one of my general population pens. I usually put them with a Heritage SC RIR male to produce Red Sex-Links. I believe because the father is a Heritage RIR and pretty dark the pullets are a little darker brown still with white. The males all look like normal RSL males. I only have 4 SC RIW older females left. I want to breed them with the Single Comb that hatched out of my Rose Combs and see if any of the chick produced will have a Rose Comb because the fathers parents are both Rose Comb. I have a RC RIW male in the same pen that the SC RIW hens are in. Soon I'm going to put the SC RIW cockerel in that pen and take the RC RIW male out. I have way too many males right now. I may send some to freezer camp.
