I figure it’s the method of getting antibodies of a COVID survivor into a current patient as quickly as possible, but unfortunately, that method, although used with other illnesses, is still a few weeks away from being available for COVID.
My hatchery always includes grow gel with my chicks when they ship. No dead chicks so far, unlike other hatcheries that did not catch up as fast on new products. It’s a green gel they go crazy for [chicks love green] ; comes in a powder they mix up with water and electrolytes or even medicine. Don’t know what the powder is, maybe agar agar or some other mucilage.
