Sure, I feed whole f/t chicks at least several times per year, sometimes more. Depends on availability.
And back in the '70s when we had a traveling reptile exhibit, I fed chicken necks, hearts, and gizzards when we couldn't find whole food in some cities. It worked great as a stopgap measure when nothing else was available. The chicken parts gave them calories, protein, some fat, etc. But we only used the parts when we couldn't find whole food. Luckily, in most cities we could find whole rodents or chicks.
The only reason that chicken breasts are great food for people is because we also eat veggies, fruit, grain, etc (and a lot worse stuff, lol!), so we are not existing solely on chicken muscle meat. If we tried to eat nothing but chicken breasts over a long time, I am sure it would cause a lot of problems for us or most any other animal.
