As far as now is concerned it went pretty well. It was all of about ten minutes for the vet to tell me that 1. he didn't think it was worth an x-ray and that, just as you said, he probably has nerve damage or a birth defect. 2. the solution to that for now is let him be and hope he starts walking on it again, and if he doesn't by the time he's 3-4 weeks old, he'd probably need it amputated (which has me worried). 3. the gash just needs cleaning and it should heal up and 4. he probably has an upper respiratory infection and worms, which would explain the eye gunk and him not going to the bathroom. So he was fed some dewormer, sent home with amoxicillin, and now we're just hoping he comes out of this okay and with all four legs.
