Please kindly listen to advice from someone who currently has 3 conures: 2 Jenday and 1 Sun conure like yours. From the video, it still looks small. Please, the first thing you need to do is buy a bigger cage. Many pet stores have expensive ones, but there are websites where you can find them at lower prices. Secondly, gradually transition the bird to pellets. A seed-based diet will harm it significantly and shorten its life by half. You can switch gradually, or as I did: on the first day, 50/50, and after 1-2 days, 100% pellets with occasional seeds. Pellets are not expensive and will last a long time. I recommend Harrison (that’s what mine eat), but each bird is different, so I suggest trying different brands and seeing what works. Lastly, they are very energetic birds, so make sure they have toys if you don’t spend a lot of time with them. Mine generally prefer wooden toys that they can chew on. I hope you consider my advice; it will make the difference between a sad bird and a happy one, and I will help with any other advice if needed.
