To answer your question with a short answer, YES, I do use a home converted stroller to walk my parrots around. I, however, also have them in a harness for their protection as well as other things around. They are on a leash while in their harness. Learning to use a harness on a bird is a wonderful tool in training. You will learn how little you really do understand your birds and how little you know how to train birds...lol
There are some wonderful pieces of information out there on how to train your bird to wear a harness. I created a stroller with vet taped wrapped safe pvc piping so they have something to grip on to. I also have been doing this with them since they were one year old, they are now 3 and 4 yrs of age.
I have NEVER had a problem with my birds getting attacked by dogs walking by on leashes, and without leashes. They are use to kids on bikes as well. I live on the beach where a lot of activity is going on all the time, the birds LOVE to get out on their stroller and will ask to do so on their own.
This is a GREAT opportunity for you to really prep and work with your birds... looking at all situations and preparing yourself with education and your birds with slow ( but not too slow) prep to go on a nice stroll. First get ready to introduce your bird to a harness. There are many types out there, I personally made my birds their own harness because I know what they like. The Aviator flight suit is a good one to start off with and it also has a leash attached ( very important)!!
As soon as I can figure out how to insert and image I will send you pictures of me and my macaws out for a lovely stroller walk, as well as a picture of us in the 4th of July parade 2012.
I do want to say, owning macaws is always a work in progress.. changes happen, so to emotions. Just like having a child, you learn new emotions and actions as they get older, not to mention hormonal issues.. with anything new, please use caution and think things through, don't be affraid to try new things, but remember, you are dealing with Macaws, not children and they can be the best thing ever happening in your life, or they can be the worst thing happening in your life, depending on how you develop your relationship.
Best wishes, and I hope this is a new beginning for you and your birds to create an opportunity to move forward, utilizing this as a way to further training techniques and learn more trust with one another.
Just want to say.. it's the journey together that counts, not the end result in record breaking time!!! Step by step is your friend......Best wishes!! ♥
