Only thing I can think to add is plastic/latex gloves for yourself and Damerow's Chicken Health Handbook. Some lubricants (vaseline, KY or even the triple antibiotic). Clean towels. hair dryer. small dishes for food and water.
But I've also noticed my fridge almost always has yogurt now, that I always have apple cider vinegar and molasses on hand.
An old glass aquarium is on the wishlist, for injured chicks, with a desk lamp over it.
Oh...and a camera so I can upload photos to the BYC.
The medication dosages is a brilliant contribution. Thank you all so much for so many good ideas.
