As a mom and having seen their faces. Please don’t kill the messenger! I suggest both

. I don’t know how many new additions you’d like, but having ordered the breeds of chicks I wanted has been a plus! I’ve ordered from the hatcheries and being able to select pullets and the kinds I wanted has been very fun!! I love a colorful flock! That said, I am a little chicken crazy and ordered a brinsea incubator (small). You could preplan an order of chicks and hatch out a small batch of chicks (this way not ending up with a bunch of roosters).
as for guinea fowl , well, there is a lot I can say on that. One, they are noisy! They just scream all day long the males honk and the females (buckwheat) that’s what they say all day long. It’s overwhelming and we live on a lot of acres. They also don’t come back at night, we had to search for them to come back , other wise the fox ate them. Skittish , flighty birds. Must have time to be chasing them .. back to the coop. And must have space, because they will end up in a neighbors property.
chickens do eat ticks
