I see normal chick poops as well.
Adding that IF a chicken does have worms it is rare to actually see any in the droppings. Chickens that do expel worms we can see tend to seem unwell, thin, droopy, lethargic and such.
Your chicks being just a few days out of the shell are very unlikely to have picked up worms for several reasons.
First a hen with a heavy worm load is unlikely to be mating or laying eggs.
IF an egg is laid by a hen that has been mated and has worms the worms or worm eggs being IN the egg is unlikely and would if there prevent the chick from hatching.
Even if the chick picked up worm eggs within hours of hatching it takes time for the parasite to grow and a young chick would likely die quickly from the worm(s) depriving it of nutrients.
I wanted to reassure you that all is well with those droppings.
