My little one is two weeks and does this . More noticeable when she is relaxing ?
Similarly, I have a 5-day old chick who keeps starting to fall asleep, then shakes her head within a few seconds of her beak hitting the towel, waking herself up. She's been laying down more than the others, and I worry that she's not getting good quality sleep. I just started noticing this today. I'll monitor the situation, but if anyone has a good idea for me, please let me know!
