Yes- I just had a pet sitter over to show her things…she does farm calls and stuff and has taken care of chickens before. I am hoping that her coming once a day is enough…and then hoping to beg my in-laws to check in too since they are only 1/4 mile away (no one understands my concern). I ordered from Crazy K but have no idea how long they take to ship. Fingers crossed. I bring my hen inside when they can't be out free ranging (so they don't get bored and peck her). But otherwise I let her stay in the coop overnight and outside with them if they are in the yard. I limited her veggies because she is obsessed with them- wondering if she is stuffing herself with veggies and treats and not her pellets. So she only gets a little BOSS and some Ultrakibble. She's such a good hen- she laid an egg in the nest box I made out of a cat carrier while inside yesterday morning!
And yes- she has free choice oyster shell- I took one of these...http://www.mypetchicken.com/catalog/Chicken-Supplies/Round-Hanging-Waterer-16-oz-p1396.aspx
and filled it with oyster shell instead and have it hanging up inside the run.
Sounds like you have it all covered. Hopefully the hen saver will get there in time. I odered some things from them too but it's been a few years ago so don't member how long it took. Quality stuff though.
