Oh Deb, you poor girl, you have come into this situation and now you have to shoulder the burden though you didnt create it.
Perhaps you can help her offload some birds to good homes, im worried about the other animals, bunnies etc.
It does sound like she has more than she can care for properly.
This happened when my 2 bunnies had a litter, I thought i had 2 girls, but 1 was a buck.
They grew and I was ready to keep all of them as I couldnt find nice homes for them. I phoned the pet welfare people who said they would come and help me and take away some. They didnt turn up, I really needed help and noone was there. I eventually found nice homes for them all and it was a relief!
If I lived closer I would come and help talk her into action, to make her life easier.
You are an angel, never clip your wings!!
Let us know how it goes.
