Nice cage and budgie. I have never seen a white one before I have the same cage for my two budgies.
I just watched the video and i noticed that you are using colored newspaper. i would recommend that you use a black and white newspaper as the color really upsets the budgies stomach or just make sure they don't chew on it
also do u have a channel i want to see your budgies and cage
I dont have a youtube channel for my budgies at the moment but i will deffinatly be setting one up in under a month or so ( when i have them both hand trained ) Ill have to subscribe to your channel when i make my one
