I too have 3 RIR's. Seeing the "official" breed specs is really interesting, so thanks to that person!
To the people who are looking to the breed to start their "chicken days", go for it, they are robust and commical in nature, i got into keeping chickens because my friend suggested it would be fun and rewarding, if i knew how fun and rewarding it is, i would have done it years ago. They prevent the need for pesticides to keep out slugs and snails, they prevent the need for fertilizers for my vegetables and they produce hormone free, organic eggs really for a fraction of the price you can buy them at the store!
I NEVER EVER thought i would be a weird chicken person, but hey i am now a fully paid, certified card carrying, pin wearing chicken maniac. I eat my breakfast with them in the yard in the morning and watch them interact with my beagle, i watch them protect the bantam from the neighbors cat and generally run amok in my yard! They are cheeky and mischivious and always looking for a treat!
I am sure all people love "their" breeds more than the next but as an all round, fun, low maintainance, high output bird to teach your kids about caring for animals and then the "reward" that comes in collecting the eggs in the morning, i am sure there is no better breed!
