I have a common feral pigeon male and an indian fantail female. They have one offspring full grown who is male. The pair are together in a large cage, the offspring in a smaller seperate cage. Im building a large coop and intend to buy another female and put them all in together. Im worried Father Pige will be too agressive - his son is rather mild mannered. Should I buy 2 females making a total of 3 females to 2 males? Would junior breed his mother? She has stopped laying eggs after having him so I dont think this is a big issue any longer. Im more worried about the boys fighting. Its a large space about 6ft by 12ft and nearly 6ft high, its an old corrugated iron lean to that Im converting. Any advice is welcome. They are just pets that I want to make happy and comfortable, I cant wait to see them flying around in their new coop.
