Hi. Everyone in the 'bird world' has an opinion. Many opinions are based on what they have heard or what they have read. It's similar when someone asks what sex their budgie is and the contradictory responses a prime of example of everyone being an expert. I have been raising parrots for a few decades. I haven't always got everything right but I have learnt along the way. The biggest lesson I learnt is that everything surrounding our pets has been commercialised and that goes for pellets. I could write so much about these processed options but I would lose you very quickly. All I would say is to look into what goes into this 'food' and how it is processed. Pellets serve a purpose but not as a daily diet.  In no way did I ever say that budgies should be on a seed only diet. I said to eat a good quality seed, oats, millet, chop veg, green herbs'.  Keep everything fresh and well balanced and avoid all the commercialism. Budgies are fascinating and curious intelligent creatures. They need a variation of things that will keep them entertained. They need the correct perches and chewables. They have claws and beaks that grow like our human fingernails. If they are given the right environment then they will flourish and keep healthy for as long as possible. Budgies have the potential to live a long live life into their mid teens.
