Tou...two Pigeons is a great number to have. It's so much easier to get to know each bird that way.
I do rescue and rehab and until recently, I had over 60 Pigeons. Last year I moved most of them to a friend's loft a state away. The ones that went to live with her, will have the opportunity to free fly, which is something they were unable to do here. Currently, I only have a few Pigeons and I really do know each bird really well. I love interacting with them and watching them.
