Chicken check??- looking good or not??

[DolceVita]

I’m new to having chickens and was wondering what breed the black chickens are and if my girls are looking healthy or not. We have had recent health problems with our LH (the 2 breeds are separated and never meet). I wanted to ask some experts about any tips or advice to keep my girls safe thanks! AND should I be concerned about the little bit of dripping comb on my LH and Black chick?

Hi, those hens seem to be in good health, as for breed they look like black sex links/ black star.
