Took a long, long time and playing by their rules only finally one crow is feeding out of hand and two more are getting a bit braver & trusting. Kinda cool .....
For sure ncsuwolf ... they have brought us gifts also showing their appreciation, like picked clean rib bones, apple core, nutello container, washer but nothing of any value.
Now that's neat. I was able to get a Rabbit to trust me over some time and she would come and feed out of my hand. She lived in our fenced back yard and we nicknamed her "Notch" because she had a piece of ear missing at the top.
