I think giving your chickens water from the rainbarrel may be a problem.
I use the water from my rainbarell for my garden but would never think of making my chickens or dogs drinking it.
Once that raindrop hits your roof think about what it can pick up, like wild bird and squirel poop.
Pollutants from the air. Heavy metals from the roof , mold from rotting leaves in the gutter, all kinds of rooftop nasties.
Also the roof itself. Some roofs are treated with anti algie treetments containing zink ot arsinate or copper.
What about misqueto larve?
I would never give my pets water i would not drink myself.
I hope your bird recovers!
