Quaker help?

Hey, new to the forum and just wanting some advice for my Quakers.
About 2 weeks ago I adopted a 3 month old blue male Quaker called Apollo and a 4 month old green female Quaker called Aurora. They are brother and sister and came from a home where they weren't trained or had much human interaction apart from feeding and been let out of the cage. Aurora has settled in the best and is slowly getting more confident with me, but I'm having issues with Apollo.

He's screaming almost all of the time (like if the wind is moving a bush outside the window, or construction is happening outside the house) and in the past day has started to pull out his flight feathers. I get the feeling that he's stressed, but I'm not sure what to do about it so it doesn't get worse. As he's started to get aggressive with Aurora and chase her along one of their perches when he's in a screaming fit and I don't want the plucking to lead to mutilation.
I've ordered some foraging toys to see if that can help while I'm out during the day and have been trying to tech them to step up (not been successful but still trying). Was also planning on letting them out of the cage at the weekend, but I'm just worried Apollo will hurt himself.

Any ideas?

Hello Pitchfix, and welcome to the Parrot Forums family!

It does sound like he's stressed. One of the things you might try is moving Apollo's cage away from the window. In his current state of anxiety, I doubt he can truly appreciate the view. You want to slowly acclimate him to life in your home, especially if he's showing an inclination toward plucking.

Were they housed together in their prior home? How large is their current cage? To comfortably hold 2 quakers it should be fairly large. In either case, if he's getting aggressive with Aurora, you should separate them. Fights between birds when one or the other doesn't have the room to retreat anywhere can get really ugly really fast.

Also, what is their current diet? Enough of the wrong kind of foods in their diet can conceivably affect their behavior to such an extent.

Other things you can do to alleviate stress are putting in toys they will enjoy destroying, making sure they get a solid 10-12 hours of uninterrupted sleep a night, and limiting their exposure to any loud or sharp noises in their vicinity. As they become more used to their surroundings, they likely won't be so easily freaked out.

Hey, thanks for the reply. I'll try and move the cage at the weekend as I'll have to rework the room a bit.

They were housed together in their last home with 1 Quaker, and they now live in liberta voyager 2nd edition for medium parrots. And I'll try and track down another cage to be on the safe side if they start getting more aggressive.

They are currently eating Harrisons parrot food (what they were given at their old home) with some seeds mixed in and the odd treat like chopped up fruit.

And thanks for the tips, trying to get them to sleep by about 8 in the evening since I have to be up by 7, might try and get them some more toys as well.
