Maybe try and few different veges and see if that gets his interest again ? I give jack snow peas, snow pea sprouts, bean sprouts, celery, baby corn and corn, apple, pear, grapes. I also give him dried banana chips , I prefer to give this than fresh banana, he never really took to fresh banana and I also found he made a huge mess, dried banana chips he loves and was so much cleaner. He also seems to like fresh uncooked beans , crunchy and he loves munching those. I also give him some parrot seeds and sometimes he gets a small amount of sunflower seeds but not a lot of the seeds.
I used to make him breakfast and a dinner each day but he seemed to just want the food I put in his bowl for the day and he has never complained once he got into that routine.. I know many make brekky and dinner for their birds but Jack seems just happy with the food I put out in the morning and any treats I give him through out the day. So I just do a mix of all the things I mentioned and sometimes I add a few nuts or some other dried fruit, he never really took to stone fruits and they always got left and mashed, so I sometimes give him a bit of dried apricot, he seems to leave sultanas.
I found cutting up everything into small pieces easier than big pieces as he tends to drop a lot of things , so its less waste. he used to be a big grape eater, mainly grapes and rarely anything else and that got me a bit scared as to whether I was doing the right thing with his diet.
I did take him to a vet and got advice in regards to breakfast and dinner and he said it really wasnt necessary and that Jack was quite a healthy little boy and a healthy weight. I dont hear any complaints from him at all, more than anything little squeals of excitement, so I know he is happy with what he gets.
I have tried mini cucumbers too , he is a bit fussy with those. He also likes chicken, but I rarely give him some. He likes to eat the same food as us.
Just dont give, chocolate, rhubarb, apple seeds, avocado and I did hear not to give them iceberg lettuce or just lettuce.
Just try different types of veges and see what happens ?
I dont know what Volkman seeds are , but if he is just eating those, maybe you should reduce it or take them away , I heard too many seeds isnt good and they can get fat , like eating Mc Donalds, but unsure if these seeds are like it or not ?
