I think they could bite. Keep hands and fingers away.
I have 4 baby blue birds in the greenhouse. About $100.00 in meal worms. This a.m. they are flapping wings and perching on a branch. I've read up on them. The father died in a storm and robins chased the mother away. I waited 40 hours before I brought them in. Still no mother and that was a week ago. I sure hope I can raise them.
