I went to the Little Farmer website...quite interesting, and their bag was labeled 5lbs, 80 oz, but the description was for a 3lb bag for $13.99 plus a flat rate $6.99 for shipping for orders under $100.
As far as the chickies go, they all hold their heads up high like giraffes when I call to them and enter the room, some even jumping high when they see me. I have no food to offer them, but they still get excited, so looming overhead doesn't seem to bother them too much. Some of them stick close to my hand while I clean the waterers and feeder, especially the Astra whites. Most of them can already fly up to the top of the brooder. I do have a pre-cut piece of hardware cloth in case they get to frisky and want to explore the bathroom. They do move over to one end when I flake up the shavings with a fork.
There is one little RIR (I call it the chipmunk because the back stripes were darker than the other two) who insists on parking on my wrist and take a short nap, then it will crawl up my sleeve and snuggle in the folds of my thick bathrobe at the elbow joint. It refuses to budge even when I softly stroke its back.
Sometimes, when they all crowd in the corner, I try to give each of them a little belly stroke...some screech, some try to run, some are indifferent.
