I hatched 5 EE chick 3 weeks ago, then bought 2 more. From the beginning, one had no use of it's left leg. When it was tiny, it would hop around on one foot but in the past week or so, it hasn't been able to get up at all. It scoots around the brooder to food and water by kicking off of 1 leg. Lately the other chicks have been sitting/standing/jumping on top of it. Not 1 or 2 but all of the other chicks in the brooder. I've checked with some local sources and I can't seem to find anyone who can/will care for it, I'm not spending the $ to take it to a vet (sorry if that sounds mean), and I just don't know what to do. I feel awful for the poor thing. I kept it initially with hopes that it would get better but that doesn't seem to be happening. I don't want it to live in pain all of the time and I don't want to wake up one day and find it smothered by it's siblings. What should I do? If I need to cull it, what's the most humane method?
