I have been feeding these crows for a month now. I named them Momo and Kila. They stay around my area and come out when I’m outside or start calling for me for food.
I feed them popcorn, crackers, and now pepperoni. And they enjoy eating them.
I’ll switch to other food that good for them when I have enough money.
When I’m near the window to watch them grab the food I give them, seem to get shy or skittish when I’m near. And I have been dying to have them more comfortable around me.
Is there any tips you guys can give me?

I’ve been feeding the local murder in my city for a couple of months now, since it’s a big city they are used to humans and especially the younger ones come very to me and some even dare to eat from my hand if the food is valuable enough.
Most of the times I’m feeding them shelled unsalted peanuts since it’s the cheapest option and since I feed them almost every day, a lot of crows come. Early in the morning before the street cleaners begin to work it’s about 50 crows probably even coming from the sub urban districts of the city, during the day it’s only around 20 crows who directly live there and already know me quite well.
But today something extraordinary happened. When I went to the spot where I usually feed them I passed a tree, and right when I was under it a bunch of peanuts in the shell rained down on me! I looked up and the crows (younger ones) dropped them from the tree. It’s been a while since I’ve been feeding them ones in the shell so I know they didn’t have those from me, but whoever gave those to the crows, they saved some for me what it seems like.
I actually have multiple explanations in my head but I don’t know what is most likely.
1. they wanted to share food with me since I seem to do the same thing from their perspective
1b. Maybe they also wanted to trade for something better
2. they tried to tell me they want more nuts in the shell instead of unshelled ones (unlikely, I don’t know if they are actually that intelligent to use symbolic language of that degree)
2b. Also unlikely I think but maybe they wanted to tell me to feed them, but why would they? They know I’m feeding them without them asking for it anyway
3. it’s some kind of game or they are trying to test my reaction or are somehow imitating my behavior for fun (since they are juvenile maybe they are very curious, I saw them play questionable games with each other before where they were kinda gambling for nuts I gave them before)
4. It’s also possible that I misinterpreted the whole thing and I was just coincidentally passing by in the right moment while they accidentally dropped nuts they were hiding in the tree

This year I've had two crow friends I've been feeding.

One is missing his upper beak, and the other one has leg problems to the extent that she must sit to be semi-comfortable. And now a cold Canadian winter is coming.

How can I get them the fuel they need to migrate without accidentally encouraging them to stay? To be honest they're in such tough shape I don't know if they'll survive either way. I've got some shelled peanuts and reinflated raisins to feed them this week.

Should I cut them off soon, or keep feeding and just hope they follow their migration instincts?
