I am soooo glad that this had a happy ending- for everyone, but especially the poor birds.

Humankind has a horrific relationship with sacrificing animals to death without their consent or desire, both historically speaking but even more so in the modern day with industry practices like factory farming and out of the billions of innocent animals that are wrongfully sentenced to death- brutally murdered around the world every week, there are no tales of victory or happy endings for them, so I am very glad that you gave them all a happy ending in your story!
You must be a real animal lover and I thank you for that.
