I would also say its a she. I had a RIR that had HUGE wattles and a big honkin comb as well. I thought she was a he. Even though I bought all pullets I thought they messed up and sent a roo. She was a mean bugger too! Nasty little thing would try and peck you every chance she got. Plus everyone said that RIR roos are known for being mean. It wasnt until I saw with my own eyes her laying a egg. So just because they have huge red comb and wattles isnt always a sign of a roo.
