Oh dear, I introduced my 2 galahs Whirly (female) and Frank (male) into a single large aviary, 3 or 4 months ago. Everything had been fine- they're not friends, but they just leave each other alone. But this morning I found Frank cowering in the corner on the ground. I put him back up on a perch, and 2 seconds later there was flapping, I saw Whirly fly at him, and he was back cowering on the ground, and wouldn't let me put him back up. I put his bowl of food on the ground for him. Poor Frank, I hope he will be ok
