As many of you know, I have one blue face male button. He is currently living with a male A&M coturnix. I also have 15 various colored button 'babies', about 4-5 weeks old. I have bought a new cage for all of them to enjoy. It was shipped out today, via UPS or FedEx, one or the other. Anyway, when it gets here, I plan on putting all my buttons in it. How can I do this to make sure there is no fighting?
