A handheld, hatchling holder not simplifies manual examinations but also better protects the hatchling's welfare. The welfare concerns include not only bruising but also yolk-sac rupture. The handheld, hatchling holder has a cupped seat portion f or cupping the ventral-end of a hatchling. The cupped seat portion is apertured, as wit h an opening. The hatchling is seated on the handheld, hatchling holder such that the cupp ed seat portion provides support to portions of the hatchling's perineal area that surrounds the alimentary vent (cloaca) as the alimentary vent is situated for exposure by the opening. The holder and opening facilitates not only welfare-friendly discharge of th e meconium in the hatchling's alimentary vent through the opening but also welfare- friendly examination of the distended innards of the vent for markers of gender. The quality of the meconium discharge (or absence thereof) also facilitates determining whether the hatchling exceeds a hydration standard or not.
