is this normal new chicks havent moved since i got them about 4 hrs ago!

In that case I'm sure he'll be right. Enjoy them they grow so quickly

Hopefully they will be girls, but I'm going to bet you have two boys and a girl.

The black leakage on the primary wing feathers of the two you can see side on - I think they are the boys.  Light sussex hens have very little black at all, and it usually doesn't show until they are quit a bit older.

Having said that, you will soon know, as the boys tend to grow a comb lot quicker than the girls.  This was my LS at 7 weeks-ish


And at 10 weeks

And at 16 weeks


(and now I'm all broody again after looking through my chick photos  )
