I'd be worried about what happens if a dog or something walks by the stroller---they're too low for my liking. Plus, what happens if she gets hurt or someone grabs the stroller? She's 'close' but you can't see her (what if she chews out or needs you) and you still have to stop holding the stroller and run around to the front to attend to her. Its also not 'attached' to you---so someone could grab it and leave. It's also pretty bulky.
Personally, Jacko goes out in her carrier, working on her aviator (and will be getting one of the parrotopia carrier handbags once I do a bit more legal research on small pets in public places---she's not ok with being alone and I think some socialization would do her good---plus she loves kids movies n tuesdays are cheap XD).
I totally applaud you for taking her out despite the risks though, it is something they need. They're not meant to sit inside the same four walls forever, or the same spot inside an aviary outside. However, I think there safety issues to remember that we often don't think about;
-Other animals, I *have* whalloped cats with sticks and avoided dogs/gulls/crows etc. Pluuus if you're like me there's always the chance your parrot will pick a fight and dive bomb the dog walking by, or the cat...or anything that breathes
-Children---- Jacko DOES NOT like children. Of course, children are often the first one to see the 'birdie' (I live in Montreal and its pretty diverse, I think I know 'parrot, mama, look a parrot!' in about 6 languages
) and they wanna come see. The problem with this is pretty much like the animals situation, and I'M at risk for getting bitten too. SO kids are told, as soon as they *MOVE* towards her, 'sorry kiddo, she will bite you, DO NOT TOUCH HER' and I pull her close to me/move away and tell their parents the same thing'
-How to correctly put this...? Be paranoid---anyone could be...sketchy. I'm broke as all heck, but people see her and assume I'm loaded. I'm a college student living paycheck to paycheck lol, but they either assume I'm rich, or the bird is valuable---either of which is bad. There was a rash of parrot burglaries in my provincce a few years ago and its on the rise. So, I personally think a birdie stroller only adds to the message. I don't walk her in areas I don't trust and I don't dress flashily. Anyone who asks about her is told she doesn't talk, she plucks, needs meds, bites and hates everyone but me and that i'm broke n living with my grandparents in a town i dont live in. Don't make her out to be awesome. Tell people to fear the beak and keep at a distance---there *IS* a black market for parrots.
