Only if "not being repelled by chicken smells" conferred a large enough selective advantage over "being repelled by chicken smells". Mosquitoes have plenty of other animals to bite besides humans, so it's not immediately apparent that it would change selection pressures at all, much less to the degree needed to push the population genotype in one direction or the other.

The most dangerous malaria mosquito, Anopheles gambiae, does selectively target humans. See:

We just need to breed a bunch if genetically modified chickens that produce L-lactic then, and we'll be set (if we use chicken odor as a repellant).
