Hello all, new here. I acquired a cage and bought 2 parakeets. Did a little reseach and saw the dowel rod perches are not good so gathereddead branches to place in cage. Live in south florida so one of branches was from a white pine. Birds love them. Have little nodes on them kinda like seeds or something that they climb over, and actually argue over best spot to chip away at. Do not know if eating or not but question is should I keep in cage or is this harmful to them. Also think I have 2 females would they be happier with a male in cage? It is a large cage so plenty room for 3 birds.
