Help I think my chicken is egg bound

[Keiki]

My australorp is 18 weeks and has not layed a egg yet but today she is walking with her tail down and keeps laying down. She has been eating normal and poop has been normal. I have never experienced this with a chicken that never layed before. Can she be egg bound with out ever having layed a egg ? Or has anyone experienced that the first egg is hard for some chickens ? I need some advice and tips please !! She is a lot smaller then my other Australorps I don’t know if that could have anything to do with it .

She can be egg boulder if her first egg is stuck. Can you feel an egg between her legs.

Is she able to poop?
If she's not, then gently feel inside her vent to see if you feel an egg.
I'd give her 1 Calcium Citrate once a day for several days.
