I'm not that well educated in pellets. I still struggle with Paco's diet. As far as hormonal exactly what is he doing? How long has he been acting like this? As for Paco's diet, he get warmed veggies, twice a day morning and evening. That would be peas, broccoli, sweet potatoes, pasta veggies (organic), yellow squash. I change it up. Fruit I do the same, a little banana, sometimes a grape and he does like a slice of apple. A slice of cucumber once in a while, it makes his poo watery. I had him on Roudybush pellets, but supply dwindled after Covid. He has a bowl of nutriberries, that I keep in his cage with Higgins California seed blend. He is 24 and I haven't attempted to switch him to pellets completely. He plucks enough as it is and I fear a change in diet will be worse. I put pumpkin seeds in with his nutriberries, from what I see on the bottom of his cage he tosses the berries out to get to the seeds. I have seen some of the pellets in the seed have been eaten as well. The amount of light, playtime and diet all add to their behavior.
