I have an interesting situation. I have the opportunity to adopt a male and female pair from a family that is going through hard times and can no longer care for their birds. What are the challenges of having four tiels in the home?
More mess. There may be some fights over territory and there's always the chance that the birds will actually repair themselves with the other birds. They may not get along and you may have to house them separately and let them have out of cage time separately as well.
