My rooster was attacked by something. We found him in the yard bleeding and covered in maggots. I tried washing him off but it didn't help. What can I do to save him,There are no vets in my area that treat poultry. Please help he is not just a ro but also a family pet.

I pulled him out, doused with DE.That was about 6 hours ago, just checked him, wound is dry and not one maggot that I can see
