1) I got 3 peafowl (2 peacocks and 1 peahen) in May and it is now August and they now come up to me and eat out of my hand. Do you think it would be okay to let them out now? Any other tricks to keep them close if I let them out? 2) I have NEVER heard any of them make a noise. is this normal? I thought they were supposed to be very loud? They are penned with some of our chickens. Just think it is odd that they don't make noise.....???
