Hi there! This is my first time posting here. I've just gotten two quails as pets, and read over many of the topics here on the forum for advice. I'm housing the two (which, according to the lady who sold me them, are both 3 week old female coturnix quails) in a 20 gallon aquarium with non-cedar wood chips as bedding, and a metal/mesh top so that they're well-ventilated. I also made sure that they have a square foot of ground to walk around on so that they're not crowded, and they have a hollowed out segment of log to hide in. I feed them non-medicated chick feed and mix in treats occasionally - mealworms and and other tasty things. Suddenly, yesterday, one of them started trying to peck at my hand through the glass, and whenever I lift the lid to feed them, she jumps and tries to attack my hands. The other is fine, though a little more frightened than usual (maybe because of the aggressive one's behavior?). Does anyone have any idea what could be causing this sudden aggressive behavior? Do I need to separate them for a day or two and see if it helps? I'm a total newbie and I have no idea what to do, but I'm afraid to put my hand into the tank now because she goes after me as soon as she sees me! Thanks in advance for any advice.
