I have an 10 week old Golden Laced Wyandotte pullet who was fine yesterday morning but come evening time was laying catatonic on the coop floor. We brought her in and put her in a box with a towel on a warm heating pad and with a heat lamp. We've been giving her water and wet feed with a straw which she seems to be somewhat interested in. She is VERY underweight, excreting bloody liquid from her vent, is breathing but won't open eyes and is just laying still. She will make a noise once in a while when i move her to keep her from laying in one position. Any thoughts on what she might have and/or how to treat it?
