I have two pairs of button quail. The first set is mellow, and calm, and generally don't cause problems. The second set is a silver male, with a brown hen. Sorry, don't know the proper name for her. Anyway, our silver male, Silver, (how original!) is very aggressive! If I put my hand in to retrieve eggs, he attacks me! I know, I know, a button can't do any damage, but he bites me! He eats laying mash, parakeet seed, and quail salad now and then. Don't worry-it's only boiled quail egg and some greens. Why is he so high strung, and what can I do about it? He is housed in a ten gallon right now, plans for a bigger enclosure in the works soon. Thank you for any suggestions. Are silvers more aggressive as a rule?
