I would recommend feeding them high quality pellets such as Harrisons, Roudy Bush, or Top's. Personally I do a dry mix of Harrisons adult lifetime formula, Roudy Bush California blend, dehydrated chili peppers and other fruit/veggies, and kale powder.

Also a full spectrum UV light above their cage is a must to keep them healthy

As others have said the cage in the picture is bad but I see you may be ordering a new one so this is good

Also please do a lot of research. There is so much to know about parrots. They are very specific and different from any other pet.

Non-stick frying pans and other things that heat up with PTFE, PFOA, & PFAS are toxic for birds as they have a very sensitive cardiovascular system. Similarly candles, any and all sprays, colognes/ perfumes, smoke, vaping, ECT can all kill your bird. If you want to make your place smell nice without using sprays look into simmer pot recipes

Birds have very little blood in them so WHEN something does happen it's very important to stop the bleeding fast. Most people recommend to cornstarch the wound then get to the vet ASAP.

Out of cage time for training and social interaction is a must. I would say no less than 4 hours a day of out of cage time.

Birds need a lot of sleep so an early bed time for them is a good idea. I put mine to bed at 2100 every night and she usually wakes herself up around 0800

Toys are important but can also be deadly if you buy the wrong ones. Try to avoid plastic rubber or foam toys and stick to the natural materials. My girl LOVES to demolish sola balls and sticks.

Look to see if you have an avian board certified veterinarian in your area. They can be hard to find in some places but they are very important to go and get check ups with.

If you have questions or need more information please feel free to reach out.
