Wattles look like cockerel, but at 8 mo, it should be sporting some nice saddle feathers.
I dont raise polish chickens, so unless its a hen feathered breed (which a quick google search didnt turn up a defite yes) I'm going to say pullet as well. A pretty well endowed wattle pullet. (it happens. I know a very large orp hen that has comb and wattles that can put some roos to shame!)
