We are taking a vacation in June~ the first in 9 years!!!!!!!!!!!
A close friend of mine is housesitting for us. She will be staying here with her dog so she can care for our dog, chickens, guinea pig (and hopefully 2 kittens by then). She is recently widowed and older and cleans houses on occasion so herschedule is flexible. We are really lucking out. She is a great caregiver and I trust her completely. That said~ we don't really have a neighbor who could do all this. But if I we had were the chickens I may have my gf up the road come and look after them.
It sounds like your girls are free-range. Do they respond to treats to lure them back into their coop? Maybe start training them a bit by shaking some scratch in a metal can and luring them in. I have a few friends who swear by this trick. Thant way your neighbor can let them out for a few hours early in the day if they feel comfortable enough to do that without worrying about getting back in time to hav ethem locked up by dusk. Just a thought.
Either way, it sounds like it will work out for you. Its great to have a neighbor's help.
Enjoy your trip!!!
