Cleaner Shrimp queston

[Beermaster]

OKay my dad got a couple cleaner shrimp today from a local fish store here in Edmonton, we dripped them into the tank over a while then intoduced them

here is what is happening, 1 of them looks like it has died, its on it back not moving right in the middle of the beach front (the LFS told him that if he see's this dont panic its just molting? now i relize that shrimp molt but right out in the open?)

the 2nd one is still upright but only moved to a different position right in the front of the tank and hasnt moved from there

does this sound normal?
