Even my friendliest hens do not want to be touched when they are molting. They do seem to appreciate a little extra protein at this time, (this helps win over even the shyest of my hens). Scrambled egg, tuna cat food, a fresh whole spinach leaves are favorites. Warning, a lot of fish may make the first few eggs when they resume laying taste like a seafood omelet, not bad, just different.
I have one hen that shakes her head when I come into the coop. I do not notice her doing it in the run or when she free ranges. For her it maybe a sign she is a little stressed.
