About 2 days ago, my dog attacked my rooster. I was able to get the rooster away from my dog but my dog gave him a good shake. Now my rooster is just laying side ways. He doesn't want to use his feet or legs. I checked for injuries and can't see any visible ones. I've tried to get him to walk, but he doesn't coordinate and goes backwards, he gets out of balance and just falls down. He was eating yesterday, but today he doesn't want to eat. He's a year old rooster. Any suggestions would be appreciated!
