You are such a wonderful person!!  I had a similar yet way-not-so-extreme case this weekend, when I went over to my DFIL's to visit....we have been talking about getting some ducks and my DFIL has more than he needs, so when I was there we saw the white crested pekins (4 total) in a dog kennel, crappy set up and they were very skittish from being ignored all the time, mucky water, no food, etc... 
 (I will refrain from saying what I want to regarding my husband's dad...he is a great man but definitely is one that should not own animals  
).  Anyways.....I am looking at these poor babies and I say to my hubby....maybe we should just take all of them.  That sealed it.  They were mine and they were coming home to live a life full of treats and kiddie swimming pools.  
So, now I have four beautiful duckies, they are about 10 weeks old and they went swimming yesterday and I almost cried they were so happy!!! 
 Still very skittish, but of course that takes time.  Eventually we will build them their own area, they are in my dog's 10'x10' kennel so they have plenty of room for now and probably the first time in their lives they ate the right type of food that ducks are supposed to eat.  I thought about putting them in with my 9 chickens, but they are SO MESSY that I am still thinking about that one.....
So, I completely understand your situation and I applaud you for it!! 
 Best of luck with it all!  And if you lived any closer I would be over in a heartbeat picking up some of those cutie brahmas
