Well here's my $.02.. if the vote is still on going!
I have both PR & BO... !!!
Now my PR (14) are a 18mo old and were our first chickens! Like you, we wanted only one kind when we started.. but that has clearly changed!! Little variety never hurt anyone! hahaha! They lay bigger eggs and I get the "rock star" treatment when I open my back door - even if I just go out to hang laundry!! hahahaha! I don't have a BR roo, but have seen some real nice pics of them! Been considering, but have too many roos already - too nice lookin to be rid of!
My BO (3 - 2F & 1M) are very sweet and puffy, or fluffy puffs if you were to ask my 4yo! hahaha! They are 6mo and the girls have been laying for a month now! They do lay a smaller egg. From what I have read, they may lay less eggs per week than a PR (PR 'bout 4 per wk & BO is 3 per wk), but they are more consistent thru out the winter do to their fluff (keeps them warmer, so they are less affected by the cold). I can EASILY pick up all 3 of my BO.. I have 1 (PollyPocket) who comes to her name and if I put my arm out, she jumps up and sits for a bit w/ me!
Whichever you'd like really! They both have their good qualities! I believe someone else here mentioned Australorps. Now, they lay 'bout 5 eggs a week! I think RIR are about the same. I don't have either of these chickens (neighbor has RIR, though - they're lovely color and disposition too!). But a variety of colors running a muck out back is definitely more pleasing to our eyes! Easier to keep track of the names too (if you have kids, that is.. they will eventually name despite what you say!)
Well, I believe that was probably more than $.02.. sorry!
Do keep us posted as to your pick! Good luck!
