I own a grey which I bought 14 days back. I dont know its exact age. I guess he will be around 1 year.He growls a lot and doesnt let anybody to come closer.He doesnt come out of cage also.But the situation has improved a lot. Now he doesnt growl as much as he did at first and also
i just heard something about . telling a tiel's sex by it nose. like you would with a budgie. i never heard of it from the bird groups or i never read it in any bird books that i have. i told the lady that you can just do that with budgies that i know of.
