Billy's beak can do some damage for sure, but she is a sweat heart, just learn to read her moods & you will keep your fingers. Spike, on the other hand is always perfectly behaved, both birds get along, we keep them in the same cage. Billy is over 27 yrs, Spike is over 17. The dogs are afraid of the birds, except for Tiki, the puppy. The birds do not know what to make of Tiki, they think he is supposed tobe afraid of them like the other 2, he is just to brave for his own good!
