I don’t think/hope these are not ticks especially since they are in groups. They seek shade when exposed to direct sunlight. Chicks eat them when the can reach. Ticks have been found on my dog (who has been bitten; negative for tick disease). But what are they and should I be worried since I don’t want to use pesticides with my chickens.

Dear pj star,
These sure look like Soft Ticks based on images posted to BugGuide. According to Everything Poultry: “The Fowl Tick (Argas persicus) may be a serious parasite of poultry if it becomes numerous in poultry houses or on poultry ranges. The tick is a blood-sucker, and when present in large numbers it results in weakened birds, reduced egg production, emaciation and even death. The fowl tick is found throughout most of the South and is extremely hardy. Ticks have been kept alive without food for more than three years. The ticks will feed on all fowl.
Fowl ticks spend most of their lives in cracks and hiding places, emerging at night to take a blood meal. Mating takes place in the hiding areas. A few days after feeding, the female lays a batch of eggs. In warm weather the eggs hatch within fourteen days. In cold weather they may take up to three months to hatch. Larvae that hatch from the eggs crawl around until they find a host fowl. They remain attached to the birds for three to ten days. After leaving the birds they find hiding places and molt before seeking another blood meal. This is followed by additional moltings and blood meals.
Ticks are difficult to eradicate and methods employed must be performed carefully. It is not necessary to treat the birds, but houses and surrounding areas must be treated thoroughly.” There is a nice BioLib image of Argas persicus that looks exactly like your Ticks.
