My current flock 2 have gotten very relaxed with each other and this allows me to feed and play with both at the same time. I can safely leave them out in the bird room and they can be both be on me as I walk from room to room. I could do this when I had 3 (with my female Alexandrine) but there was more posturing and screaming. My Alexandrine female was jealous and would give the others a hard time now and than. I don't see that with my BC Conure female and female LC Amazon. Not sure if it is the species or just that 2 parrots is company and 3 is a crowd?Do you feel that 3 is always an odd number of birds to have if they are all single? Lynne
