I would suggest only rewarding absolute correct behaviour otherwise it will be confusing
He'll work out the difference.
As to your family, never let him perch higher than them.
Make sure they Begin to eat first. If he is a problem then shut him away.
He is trying to be higher up the pecking order and needs to learn his place.
Have your mum get him out, so he only comes out if its ok with her
If you cover him at night, ask your brother to uncover him.
Hope this is helpful.
Had a training session with him earlier, he was really good for me, even got him to touch the perches I was holding, however when my mom got back in I got her to do some training and whilst he will copy noises for her the moment he was asked to step up he warned her, she persisted and he bluff lunged for her so she backed off, did noises with him and again was fine with her.
I asked him to step up afterwards when she was done and he was right over to me, so I tried to get him to step onto my mom from me and he decided to go back in his cage instead.
After my mom left he came back out again and we did more training, then when my dad came in he walked past Rocky and Rocky warned him as he was going into Rocky space (he has a perch set up for out of cage time but it doesn't leave much room between the perch and the table you have to get past), when my dad ignored this he bit him, got the back of his jacket, my dad turned round and stared at him which I kept telling him just to back off but he doesn't listen half the time, when my dad had to walk past him again Rocky warned him and again bit his jacket. The third time my dad had to walk past (he was going in and out the garden) he was carrying some stuff so I told him to wait whilst I got Rocky on my arm and out the way but he didn't listen and just walked right up to and spooked him, needless to say Rocky wasn't too keen on any training after that, but as soon as my dad left he was fine again.
As for your suggestions, he is only get rewarded for the correct behaviour now, thanks for clearing that up
He is not allowed to perch higher than us, he occasionally goes on top of his cage when he is spooked but comes down when asked. He is not allowed on shoulders only forearms.
We all eat before him, they don't normally eat in the same room as him of an evening however but on days when they do we eat first then he gets his bits, unless he is out with me at the time and he is allowed to eat from his dish when my food is ready and I am ready to eat and I call him down to it.
Shutting him away when he is a problem is a problem in itself however, he behaves for me no problem it is when I am not there that he will not listen to them and he will refuse to go back in his cage for them.
My mom gets him out but he will still not step up or go back in for her no matter what she tries, she had to leave him out for a whole day while I was at work as he refused every effort to put him back.
My mom uncovers him first thing and gives him a grape which apparently now drops rather than eats or he throws it back at her.
I think after how he was today everyone is getting a bit wary of handling him to be honest, I do insist they don't handle him if they are nervous as this makes him nervous, I just don't understand why he has gone from stepping up for my mom to suddenly warning her everytime, even if she asks him to fly across to her rather than putting her arm in his space he warns her.
Would really love to know how he was treated as a chick.
