Abnormal head movement

[Bonnieboo]

My lovely Australorp, Gertie has been acting strangely in the mornings for about a week.
When I open the coop and they come out, I give them (4 hens) about a cup of scratch mix on the ground.
Gertie is a real guts, and could eat underwater, but this last week after a couple of half-hearted pecks, she jerks her head backwards while taking a couple of steps backwards. She then goes back to the seed and then again does this strange backwards dance, jerking her head.
She is eating, pooing, drinking and behaving normally the rest of the time. She's deep into a moult and has just been treated for scaley leg mite with ivermectin (she was doing this before the treatment) so I just can't figure it out.
Have I described it well enough to create a mental picture? I seriously am confused by this behaviour. Any help would be appreciated.

Chickens can act pretty weird when they're molting. Some I've noticed weird poo, some it's weird behavior, some both. If she's eating, pooing, drinking and acting normally and seems in otherwise good health with no discharges around nose or eyes and there's no pests like mice or lice on her head or body - then I'd just monitor her. You could give her something to help her out thru molt and being treated for mites with medication. Like brewers yeast or b and e vitamins, poultry vitamin boost supplement, feather booster feed or supplement, there's a variety of products for this that might help as molt is a stressful time for a chicken.

Thanks for your helpful reply. Would not giving them some meat (protein) enough to help while regrowing lost feathers?

Extra protein would help with regrowing feathers but she may need some extra vitamins like b and e too. I usually give mine nutritional yeast during molting, seems to make it go easier for them.
