Looks like I've gotten myself into a pickle with a new button quail that was given to me for free. So, this little male bird is around 9 months old. The lady who gave him to me originally bought him as a single bird from the pet store, and was told that the female(s) he was with died, so he was the last one remaining. I've had him home with us for about a week now, keeping him separated but within view of our other birds. I have a couple of females that are around 3 months old now, so I thought I would try and pair him up with one of the ladies. I have a separate cage that I thought I could use to introduce new partners to one another, so I have been trying this with the new male bird. Yet, with every female I've introduced, he immediately attacks them - grabs their neck by his beak and holds a vice grip on them. Holy crud, I've never seen a male button quail this mean and aggressive. I'm kind of wondering now if this guy may have been the reason why the former female he was with died under suspicious circumstances. Anyone have any suggestions on how to introduce such a bird to another female with better success, or have any experience with this kind of situation?
