my appx 17 yr old bird has recently (last two weeks) started going to the bottom of his cage, forraging, ripping up the paper flapping his wings, this behaviour is going on thruought the night so he is getting no rest he no longer wants to come out of his cage he is now very skittish and obsesed with his new routine, he’s still eating and toilet are the same as they have been we have had no visitors or change in his routine i am concerned that if i take him to a vet he is prone to fits so do not want to add any undue stress but am very worried about this change in his behaviour as we have had him for years please can you offer some advice on this matter
