I dont think its an easteregger. It looks more like a columbian rock or if its an easteregger its not bearded and has a single comb. It IS a rooster though.
I would guess a mix breed of some kind. Maybe a colombian rock mix. I'm not convinced it's a roo though.
Probably some sort of hybrid, not sure which. But definitely a pullet. A 2-3 month old rooster would have a bigger comb and wattles than that by now.
