I'm not sure if this belongs here, so please let me know if it should be moved or removed.
I took in a nestling house sparrow a few weeks ago, I think he's (unsure of sex) around 4 weeks old now and appears healthy. Usually he's pretty calm, but sometimes he'll just run at my hand and start really having a go at my finger, even breaking the skin. I'm not sure if it's true aggression or why he would be doing this, nor how to stop it.
Any advice greatly appreciated.
