Straightly coming to the point, the only breeds that can't raise as lovebirds colony are Abyssinian Lovebirds ,and Madagascar Lovebirds. Yes!!! You can breed Black Masked, Peach Faced, Nyasa, Fischer's for effective colony building.
You should bred in the aviaries as such 5 pairs per aviary. You should put a flock at a time. i.e. 5 pairs at a time rather than introducing pair by pair to form a colony. If you introduce the birds pair by pair, the dominant one will try to fight with other males and there is every possibility of death of the new comers.So, to build a lovebirds colony, it is always to raise a total number of birds at a point of time. ALL THE BEST!!!
