Lethargic,wings drooping, face pale. Light brahma came out of coop this way this morning. She seemed fine yesterday. She is drinking and eating some but not normal. There was white urates under her vent. When she pooped it was firm but had undigested grass like texture. They do not have grass in the run. Yesterday I gave them a half of a spaghetti squash to share between 18 chickens. Any ideas?
