Your survey is a bit biased, particularly the second page. You're coming up with a solution for a problem that you haven't yet fully understood. I recommend you ask around about what people's thoughts about cleaning cages to be, how they feel about it, why they do it, when they do it, how they do it. It might uncover some interesting findings that might shape how you approach this. I've seen many clients go in without such basic research, only to have their products fail when hitting market. By the time they come to me, it's too late because their whole premise doesn't match their potential users' wants/needs.
I realise surveys are inherently more quantitative, but try gathering some basic qualitative insights before validating your idea with quant data.
I would also suggest for your survey to do a bit of research first - budgies and cockatiels are both parrots. Are you perhaps thinking about size difference? Or what is the purpose of that question? Are budgies' vs cockatiels' messes different enough to warrant that segmentation? Think through the purpose of your questions first before crafting them; otherwise, you'll end up with meaningless data.
Now, speaking as a potential user, I would not use a self-cleaning cage. Why? A few reasons.
Let me ask you: How do you tell if your cockatiel is healthy or not? Is it just based on looks? A bit dangerous since avians hide symptoms better than mammals do. And I know cat owners who reject self-cleaning litter boxes for the same reason. Their droppings is sometimes the first indicator that something is wrong. By the time they start fluffing up and sleeping constantly, they've often little time left.
Next thought, if there are toys in the cage or food being fed there, how can you tell if your bird is consuming it or tossing it to the bottom of the cage? Yes, toys should be found at the bottom of the cage - you don't want your bird ingesting anything. And food ideally should not be all at the bottom of the cage but eaten by the bird (some birds will forage without eating).
Another thought, when our little guy started vomiting, he started at night. The next morning, I went to clean his cage and saw it clearly. We rushed him in the same day. Ultimately he was hospitalised for that illness. If I hadn't seen that, we wouldn't have been able to catch it early enough to be able to conduct tests on him (once a bird is fluffed and sleeping constantly, they're sometimes too ill to be able to conduct test without stressing their heart to the point of death). Our vet commented that it was fortunate we didn't wait for his symptoms to get worse and that we were able to get an appointment within the same time.
Finally, a small part of the concern would be, if not newspapers, what other sanitary way? Birds can get into things all too easily. Most newspapers are not going to harm your bird if they manage to pull it up through the grating. Cat litter and other similar substitutes can.
Hope to see what insights you can take away!
