-several days later- Snubby is eating seeds from standing grass. I sprinkle food on the ground for him. He hangs out with the chickens now and is not afraid of me, probably because he was raised just four feet away from me at my window feeder so he is used to my movements. He's always around and looks me in the eye while I talk to him. He spotted his dad today and went to him begging but got chased off. The dad has cut the cord and Snubby is on his own. He looks like a female at this point but they usually do when they are young so it's hard to tell. I will continue to call it a he.
-next day- Snubby has disappeared and I woke to a cat hunting at my feeder. Snubby had two close calls with this persistent hunter earlier in the week and I figured it was just a matter of time because Snubby is unwary and hangs out on the ground. I got up at sunrise every morning to chase the cat away because that's when it hunts but I slept in today and fear the worst. Knowing a bird is a privilege and I was looking forward to seeing how the relationship would evolve. But if Snubby was eaten at least he/she won't be laying eggs in anyone else's nests next year.
Here is a little video of Snubby waiting at the door for meal worms.
