Pet Sitter - Full-time / Part-time

I have an older dog, Jack Russell mix, a 3-year-old Siberian Husky and a Bernese Mt Dog who is a 4-month-old puppy. I have one shy cat and 8 chickens. I need someone to come once in the morning and once in the evening and feed and water the chickens, check on the dogs and make sure they are all well. There will be our son, 22 and daughter 19 at home after work and some days at home and they will be feeding the dogs and cat but I need someone to check on them twice a day and feed the chickens twice a day.
