Maybe also put his favorite treats inside some foraging toys so that he has to work and chew to get them.
Have you seen a vet just to make sure there's nothing more going on?
What things did he chew on previously?
Ok thanks, I’ll try the foraging toys, he throws his toys around fine, climbs , cracks sunflower seeds all well His cage and our living room, where he is out all day , is full of poplar, lilac and maple climbing things and perches The only thing I can see is our coffee table has natural oak legs, that I knew wasn’t ok for him to chew on so I put socks on the legs. But he got scolded for going there before I thought of that idea Maybe he thinks chewing is a bad thing ? When he was young he chewed though a poplar perch twice! No problem
