Baby chick is quiet

Hi everyone,

My baby chick is eating and sleeping but sleeping a lot during the day and is quiet.

She sleeps during the day too and doesn’t seem to want to forage.

I don’t see anything visibly wrong with her.

I don’t know exactly how old she is but I am going to guess 4 weeks.

Should I be concerned that she is sleeping a lot?

Is she also an Easter egger or an English hen?

Does anyone know her breed or estimate age please?

I did notice when she is standing her tail is droopy abit. Is that anything to worry about?

Thank you for helping me.
