Roo or no?

[EggspelliarmusBellachicks]

Hi everyone! I got a group of (all female apparently) Sapphire Olive Eggers from our local Tractor Supply a little over two months ago, but am thinking that one of them, maybe two, are actually roos. We’ve heard what sounds like possible crowing a few times in the morning within the last week, and it looks like both might have some spur bumps on their legs. These two are also larger than the others and have larger combs/wattles. I tried to get pics of both of them which I’ve attached, but if anyone can help me with figuring out whether they’re roosters or not, I would appreciate it!!

Yes those are definitely both cockerels.
Sapphire Gems are supposed to be sex links. Females are blue and males are blue barrred.
Do any of your others have barring or are they all solid blue?
