I suppose the only way I'll know for sure is to wait another couple of weeks for them to both start crowing - then I'll have my confirmation!
For me, #1 should be really stunning (given he already has nice white "fanned" tail feathers - which I'm guessing (being the unintended chicken novice that I am) will only get bigger as he gets older). When he was a bub, he was a very pale yellow and we thought he was going to be a white chicken... oops, glad I didn't put any money on that one!!
So far the definite rooster (whose head is in one of the shots with #1) has started to crow from 7:10am. He has only crows 5 or 6 times and is as quiet as a mouse for the rest of the day. Last night we moved all 3 of them into another shed which has 1 window (which we have "blackened out"). Not one peep out of him until they were all let out at around 8:15am. I'm hoping this "limited + reasonable hour" crowing won't generate any complaints. It's not like he's crowing all hours of the day and at 4:30am!! Hopefully this "black night shed" idea will help control all of them for as long as possible - well, until good homes can be found for them.
Another question: what has everyone's experiences been with bringing a lone "stranger" rooster amongst a flock of hens? My concern is even if we find each of them a home - there might be a personality clash with the hens they end up living with and the new owners might just go "hey, this dude is attacking our chickens, off with his head!!" (which I obviously don't want to have happen).
