See, I thought we had a simple routine - the only tasks needed: open/close door, refill/watch outside waterer since its 90+ degrees out, dump out a bowl of already made fermented food, get eggs. They have access to dry food and water inside of their coop 24/7 and that holds at least 2-3 weeks worth of both. I guess with the autodoor that takes out a huge portion of the tasks.
I don't know; I guess I just thought since I was paying someone to stay at the house (on top of stocking the fridge for them, 2 bottles of wine and snacks - and them drinking an entire bottle of expensive tequila) and they only had to watch the chickens & water the gardens if it didn't rain - I thought they would follow through with what I had asked.
Sorry your pet sitter didn't follow instructions and sounds like they took advantage of the situation a bit.

We didn't have an auto door before (we've only taken 1 trip since we've gotten chickens) so we had asked the neighbor to let the chickens out in the morning, close up in evening, and pick up eggs (with auto door now it's just eggs). As she's elderly and her husband is ill I wanted to keep the instructions as simple as possible.
