We are going to be gone for ten days over Thanksgiving and have arranged for a friend who also has chickens to take care of ours. We are both new to the chicken game, though, so I've got some questions about what to tell her. I want to make it as easy on her as possible without harming the chickens. The chickens are abou three months old, if that matters. 1) Will they be okay locked inside the henhouse for that long? Three chickens in a 3 x 5 henhouse. They do have a very secure run, so she could leave the chicken door open, but that would mean a draft inside the henhouse at night. I'd like for her to be able to check on them every other day. If she has to open and close the chicken door, that means going over there twice a day. 2) They have a two-gallon waterer on a waterer heater. What would be the minimum number of times she will need to change the water in ten days? It doesn't tend to get much junk in it but I just got it so I'm not sure yet how long it lasts. 3) What other instructions would you give a chicken sitter?
