That's a shame you can't keep him.

Roosters are a great addition to flocks and all these people just talking about aggression is sadly not the case. Sure they can be aggressive but you can teach them, but it takes a lot of time. But none of my roosters from day one have been aggressive towards me, pets, strangers, or even the other chickens. NONE. And I had eighteen at one time. (11 have since been rehomed.) So everyone is screaming aggression, but he could be different, only time will tell. But I'm awful sorry he's a roo. TSC did the same thing with one of my Cuckoo Marans. Pullet bin, sweet cockerel boy. And I really hope that isn't the case with my EE's.

Best of luck!
