I have used this product before. My cockatoo loves these brightly coloured food shapes. I mix them with her regular mixed parrot food to ensure she gets all the nutrients she needs. I would advise introducing them gradually to regular feed if using for first time.
I was very happy to purchase these sticks, having given similar from my own Balti mix. She loves these and they come in handy packs you can transfer to a sealable tub to keep fresh.
Five stars I award and highly recommend for cockatoos.
