No? I cringed reading it. Eating whole animals instead of individual muscles is one thing, getting to them mid-gestation is a whole other level of body horror for me.
Poultry is regularly prepared whole. Thanksgiving turkey, Peking duck, and simple roast chicken. A Cornish hen can easily be polished off by one person. Chicken eggs are regularly consumed. There isn't anything weird about Balut, just that it's unique.
You'd carve the meat off the turkey, after removing its innards. The bones might be used for broth later, they certainly wouldn't be eaten at the same time.
It's not typical to eat the bones, muscle, and offal together.
Oysters are just as slimy and all over the place, but they are what they're supposed to be. Everything is in the right place. They're complete. Fetuses are a whole other ball game. I'd rather eat those whole French songbirds or whole octopi or insects before I got anywhere near a half-gestated anything.
