You did good. High quality bird seed would have been a good option for it as well.
You did very good.
I read an account of a tree of squirrels that cut the guts out of a dog that was barking at them. Very sad for the dog, because it likely meant no harm.
But this is a cute story that was posted here a few weeks back.

No, a baby robin cannot survive on bird seed, probably wouldn’t eat it, either. The hamburger and berries was a much better choice.
These babies had their parents helping them forage. It’s hard to go out these days to put out food, so I’ve set up a multistage unit with a ladder to the table, the highest level just under the library window. That way I can do all the feeding from the window. The raccoons sometimes eat with the skunks on the ground, and sometimes go up to avoid them.
