They are not sexlinked. The chicks from her are yellow because she has the dominant white gene as evidenced by the white markings she has in her neck and tail feathers. Dominant white turns black feathering white and leaves reddish or gold tones as is. I am not sure what her e-allele gene is, but the father's coloration is birchen-based, ER at the e-allele, which is dominant over most other e-allele genes and makes mostly black chicks that feather in later with those reddish markings. So, the chicks inherited birchen from their father, making their chick down mostly black, and they inherited dominant white from their mother, turning that mostly black chick down into mostly white. I hope that makes sense! None of those genes are sexlinked, so nothing about how these chicks look will tell you if they are male or female.
With sexlinked crosses, yes, males will typically resemble their mother more than their father. This is because sexlinked genes that hens have can only be inherited by their sons, never by their daughters, due to how the sex chromosomes are inherited in birds. Their overall appearances really depend on all of the genes at play, though, not just the sexlinked ones. For example, a common sexlink cross is a Rhode Island Red rooster crossed to a Barred Rock hen. In this case, the sons are barred like the mother, but the daughters are not red like the father; instead they are generally mostly black with some reddish patches, really resembling neither parent. So the girls favor dad boys favor mom thing is not really the full truth of it. You have to look at all the genes involved, not just the sexlinked ones.
