This may seem harsh...
Well, first of all, passionate parrot owners are aware of the dangers of feeding a seed diet to their birds, so if it's primarily a seed mix, it doesn't matter how pretty you make the packaging, if I feed that to my bird long term I will destroy his/her liver, so I am not going to buy it... :11:
I will put it down and walk away.
If you're selling seed mixes, then you need to find out what IGNORANT parrot owners, who don't care about the health of their birds think... they're the ones who buy based on pretty packaging and advertising claims.
Sorry, seed is only about 10% of a parrots diet. If it's 75% of the content of your bird food mix... well, it's not something I'd give mine.
Parrot owners are a lot more sophisticated in terms of ingredients/what we feed because the pet food industry has been marketing stuff that has long term bad health consequences for our birds for a long time... Diet and nutrition are absolutely critical components to captive bred birds, and most people are smart enough to know that.
Your packaging should be focused on concisely what's in it, and how is this more beneficial for my bird's health than anything else on the market. We're pretty bottom line people.
There tends to be a lot more involved taking care of a parrot than there is taking care of other animals. So, we do tend to be more informed.
