oysters
Oystercatchers do not primarily eat oysters, despite their name. They mainly feed on mollusks, such as clams and snails, as well as other invertebrates found in intertidal zones. Some species of oystercatchers may occasionally consume oysters, but they are more adept at opening softer-shelled prey. Their diet varies based on habitat and availability of food sources.
Oystercatchers are found in all the continents exept Antarctica
it eats a variety of invertebrate marine life including mussels , whelks and limpets
Variable oystercatchers eat several types of marine organisms. They mainly feed on organisms like earthworms, marine worms, crabs, and mollusks.

First eggs are often undertended and lost (up to 40% among Eurasian oystercatchers), and parents incubate alternately and continuously for 24-39 days.
Variable Oystercatchers primarily feed on marine invertebrates such as mollusks, crustaceans, and worms. They use their long, sharp bills to pry open shells and probe into the sand for food. They may also feed on small fish and occasionally on plant matter.
Oystercatchers are striking, black and white wading birds with long bright red bills. Their bill is used to break into shellfish, and each individual inherits a particular technique from its parents. Despite the name, oystercatchers are not known to eat oysters and in fact favour mussels. They supplement this specialised diet of hard-shelled molluscs with softer-bodied invertebrates, such as crustaceans, worms and insects. Oystercatcherd are primarily shorebirds, although they do sometimes breed inland by rivers and lochs. They are more usually found at the coast during the winter
The scientific or taxonomic name would be Haematopus spp.
They generally live for 12 years or less but have been known to live for more then 40 years! Source: BTO

Chickens will try to eat almost anything and everything, good and not good for them. They may try to eat mushrooms but do not let them, mushrooms are bad. You will end up with sick or at the worst dead chickens.
