Prepare an ice-water bath; set aside. Place 6 eggs in a saucepan large enough to accommodate them in a single layer. Fill with cold water, covering eggs by 1 inch. Bring to a boil over medium-high heat. Remove from heat. Cover; let stand 11 minutes. Place eggs in ice-water bath; let cool 2 minutes. Gently press eggs against a hard surface to crack shells, then peel under cold running water.
Put pork, 1/4 cup breadcrumbs, 1 raw egg, thyme, allspice, salt, and pepper into a medium bowl. Using your hands, mix until combined. Using damp hands, break off a 2-inch piece (about 3 ounces) of meat mixture, and flatten into a patty. Place 1 peeled hard-boiled egg in center of patty, and work meat mixture up sides until egg is completely enclosed. Repeat with remaining meat mixture and eggs.
Dust each wrapped egg with flour. Whisk together remaining raw egg and the milk in a shallow bowl. Place remaining cup breadcrumbs in another shallow bowl. Roll eggs in milk mixture and then in breadcrumbs to coat.
Heat oil in a large, heavy saucepan until it registers 360 degrees on a deep-fry thermometer. Working in 2 batches, fry eggs until meat mixture is golden and cooked through, about 6 minutes. Transfer to a plate lined with paper towels; let drain. Serve warm or at room temperature.
