Best Pet Birds

I want to raise Pet Birds?

I am going to own a pet SUPPLY store (well, practically supermarket). I do want to have some live animals there. I am going to raise mice and rats primarily for food (reptiles gotta eat too!), but you could get them for a pet. I also want to have some birds. THey will be hand fed and raised in my home. When they are old enough, they will go to the store and be for sale. Would just having nanday, sun, golden capped, and blue crown conures be good? Or should I have Budgies and Cockatiels too? Note; I will NOT be an evil bird-mill. I am going to have just one or 2 breedign pairs for each species, so a couple babies of each kind available, and not available at all times. ARe conures generally good breeder in captivity?
Did I say I was going to go open a store tomorrow? No. I’m not an idiot. I know you need to learn from someone very experienced. Before you ramble on about stuff you just assume, could you please just answer my question.

You are in the wrong place to try to learn everything you need to know before even thinking about taking on such a task. First off, you don’t raise “pet” birds. Birds are not pets. What you try to do is raise chicks that are accustomed to humans and hope that you can build trust in them so they won’t be frightened all the time. You need to get with a local reputable breeder and start learning from them. If you are running the store, who is going to feed those babies every two hours around the clock? Who is going to be right there is a problem suddenly develops like slow crop, crop stasis, impacted crop or any of the other many problems that can come up when novices try to raise birds. I applaud you that you don’t want to be a bird mill. But if you don’t get very researched and educated before you even begin, you could end up being just as bad as a mill with only one breeding pair. It’s how you house and take care of them that is more important than how many you have.
