Crowing
@wildone, there's a huge difference between raising a robin from a puffball stage and raising one from birth. The naked, just-out-of-the-egg stage is the most vulnerable time in a baby bird's life. Also, I'm skeptical that egg and nothing else fits a robin's nutritional needs. When you say it "did fine", did it feather out properly? Are you sure it was healthy when you released it and not just surviving?
