I have four week old chicks! I had them outside most of the day yesterday and they were doing great! Last night they were lively and doing well. Now I have a bird that is very lethargic and looks to have blood on butt and beek. My other girls are doing well but seem like they have the poops. Store doesn't open for two more hours what can I do to help! I did take the weaker of the bunch out of the flock and gave surgar water. What else can I do! Please help!
