My chick are 3.5 weeks old. I want to go away for a few days but I don't know if I should. How long do you guys leave you chicks or chickens home alone? How much water and feed do u leave them? One problem I run into is I feed them water in a bowl and everyday they (8 Chicks) get the bowl very dirty. If I leave for three days I'm thinking there water will not be drinkable by the third day. Any ideas on how I can keep there water clean for a few days?
