Well said!
Do you know what your bird died of? I personally never place a bird in a home where a bird recently died unless there is a really good explanation or a necropsy has been preformed to rule out illness or environmental causes.
Can I ask why you mention both CAG and Mac? Those are vastly different birds; so you have experience with either species? Also we should ask; what sort of bird was it that you had before?
I should also ask, what is your schedule and living situation like? Any bird being regimes for free is likely free for a reason. Usually any free parrot will need EXTENSIVE work to even get them to the point of being mildly pleasant to live with. Do you have the experience, time, money, and space from neighbors to deal with a chronic screamer? Vicious biter? Self mutilator? Extremely ill bird? Birds that are good pets usually either don't lose their homes or have pretty hefty rehoming fees attached.
You would be surprised how many people say to me directly what you have posted, since I often have fosters as well as the babies I produce. I have to be honest with you here; the ability to pay the initial price of the bird is sort of a test of your financial ability to care for the bird. Sure you might have the cage already and money for food, but what Beatrice said about vet bills is no exaggeration. I spent around $1500 at the end of last year on a bird that died anyway, despite the best efforts of 5 different vets, every relevant test, medication, supportive care, everything we could do. But I have other birds who have cost me thousands and lived. I've spent more on vet bills than the cost of my car, and that's coming from someone who is educated on parrot welfare, health, nutrition, etc and does "all the right things." It would be less concerning if you said you didn't WANT to pay a large rehoming fee, but you said you CANNOT, and to me that's way too huge of a red flag to ignore

maybe the right thing to do in your case is to wait a few years until you are financially stable and can afford the proper care of the bird you are looking for.
