Has anyone or does anyone keep Parrotlets in a colony aviary? Meaning just with other P'lets not a mixed species aviary? This also wouldn't be a breeding setup, so no worries about territorial mating behaviors. If you've done this or thought about it, what are some tips? Equal number of males/females? Only one sex? I'm thinking 6x6x7 for the size- surely that's big enoug, yeah? Several feeding/watering stations and perches/toys to avoid territorial behaviors. Let me know what you think.
