Need help quick! Dead bird!

[nicole camp]

I found my lavender orpington chick dead yesterday afternoon with blood all over the brooder. The blood came from her butt and she had a very quick death no more than 4 hours after I had left. Need help quick! If anyone has any medications or remedies please post. The bird was a young pullet fully feathered
