Turkey eggs are not as often seen on the market as chicken eggs.
This is due to several reasons.
First, turkeys lay significantly fewer eggs than chickens. A single turkey can lay about 100 in a year, while a hen can lay more than 300. This means that turkeys are not a profitable choice for testicle production on an industrial scale.
Second, eating turkey eggs is not as common as eating chicken eggs. They have a larger size and weight, thicker shells, high costs of their production, and, accordingly, the cost. The price of one turkey egg is 5-7 times more expensive than a chicken egg, which is not attractive to most consumers.
Third, to conserve turkey stock, they are used to raise chicks, so their production is limited.
However, for those who want to try something new, turkey testicles can be found at specialty stores and farmers markets.
