I found found a poor little injured adult robin yesterday and he seems unable to fly, appears to have an injured leg (he/she waddles),and constantly poops out a yellow ooze. So yesterday I made a 12 inch x 24 inch box that's about 12 inches tall, to put him in and then I put some leaves and stuff in, and i gave him some fruit, peanuts, and water. But when I went to see him today he seemed really weak and it looked as if he hadn't touched his food or water. I live in the wilderness pretty much so there is no one I can bring him to, and I don't want to release him otherwise the raccoons will get him. Any input would be very much appreciated, thanks in advance. I don't care about the legal repercussions by the way because he would die if i didn't help him.
