4 week old chick stumbling around. Please help!

[Haleyrbloom]

She is going down hill fast.
She now has blood patches and looks to be in pain.
If it comes that I decide to put her down, how can I do it humanely? I have put down an animal on my own before.

I am sorry that she seems to be declining and seems in pain. Many people use scissors or a sharp knife to take the head off quickly. With small chicks I have used an airtight container with equal parts baking soda and vinegar which puts them down with in a minute or two from carbon dioxide poisoning. You can also use car starting fluid which is ether to put them down in a similar way.
