Issues with bantam chick/ should I be concerned?

[Myah1011]

I have a small cute less than a week old Mille de Fleur Bantam chick who’s name is Moth and I notice that she tends to fall down whenever she’s preening herself and struggles to get up again, I have also noticed that she gets run over a bit by her bigger flock mates (only 2) and sleeps quite a lot, I have probiotics and electrolytes in the water and a good crumble for her to eat, she eats drinks and poops, she doesn’t seem to have any balancing problems until she preens time to time, she’s also gotten pasty butt recently if that correlates, she doesn’t seem lethargic just really sleepy, and the temp isn’t too hot or cold, I did put a towel in there with her so she doesn’t fall down as much but it still happens, should I be concerned at all? (Currently can’t sleep cause I’m afraid she’s gonna fall over and not be able to get up) am I just paranoid???
