Hi Aqua,
Thanks for rescuing this little sweety. Bragg's raw apple cider vinegar is what
is most commonly used in terms of ACV. The raw ACV has what is known as the "mother" in it, which in itself contains probiotics and additionally, the acidic environment is what good bacteria thrives and multiplies in. Four tablespoons though, is a bit high...even just one tablespoon will provide the necessary acidic environment, two would be plenty for routine maintenance.
I'm tapping on the wisdom of Gordon Chalmers here on the amount.
It wouldn't be uncommon for a pigeon to have worms, canker (Trichomonas)
and Coccidia are also usually present though not necessarily in a disease state. Both Canker and Cocidiosis are present in what's known as a "host equilibrium" state, and when a bird becomes stressed for a variety of reasons, then one or both of these can rise in organism population and become a diseased state. Just something to be aware of for the care of your new companion.

I have also seen some of my birds do the head shaking thing and beak gaping...sometimes the gaping can be as simple as having just finished preening, sometimes it can be worms. Medipet has a wormer that's pretty
broad spectrum and safe, here's a link;

Ivermectin or Moxidectin (Scatt) are both good for protection against round worm (only) and external parasites that feed off of the blood.
I would be concerned about the issue w/the leg and knee. What we don't
know is if the problem truly stems from an injury or is this a form of Articular
Salmonella which would require treatment. The poops do look good and that
is promising. I'd keep a close eye on the bird's over the next few days and
see if the bird is navigating any better with a few days time and keep folks here posted w/progress updates on your bird. Also, a handy technique for
new comers when medicating or assisting w/eating is what Dr. Shuckman
refers to as the "Bird Burrito". You take something like a hand towel or
pillow case, fold it length wise and wrap the bird up so that the wings are
immobilized and the head is sticking out the top.
Hope this helps,
