A friend hand raised a baby pigeon in her bathroon until it was about 9 months old. The female pigeon started to lay 2 eggs each month and I think took my friend to be her mate. It became very difficult for my friend to spend enough time with the pigeon and so she asked me to look after her as I also have had experience of raising pigeons. Penny is now just over a year old and is becoming very attached to me although she has not produced eggs since being here (3 months). At the moment she is living in my house whilst I am building an aviary (3m x 2m) on the terrace. I intend buying a male pigeon to keep Penny company but am afraid that as she doesn't probably know that she's a pigeon she may fight him off and both of them get wounded or worse! Does anyone have experience with this kind of problem. I would also appreciate some help with designing their living quarters, size, openings etc. It can't be too big as it would take up too much flight area. Thank you to anyone who could give me some advice.
