I'm thinking it's a roo too. Well I've found a good home for both if they in fact are roos. But it's still so sad. I've gotten SO attached to them. Thanks for your help. Maybe it's a pullet with extra testosterone LOL!!That's some pretty significant wattle development for one so young.
If pushed for a guess, I'd say cockerel. Sorry.
I hope I'm wrong for your sake.....
