I recently combined two cages into one large one. I have two male cocketiels who are basically the odd couple. They don't really like each other but they tolorate each other. I put a pair of parakeets in with them. They got along for a few days, but this morning I woke up to blood and feathers everywhere. Not sure who was doing the fighting but one was a cocketiel because he was the one who was bloody. Is the one female going to cause problems even if she is a different species?
