Were the 1987 TMNT actually brothers?

You know, aside from Next Mutation that went out of it's way in order for Venus to to be at the center of a love triangle its not addressed formally.


In the 1987 cartoon both Michelangelo and Raphael have birthdays on different days so they might be born in different clutches if they are actual siblings. It's possible that the four of them have the same parents and each came from the 4 cluches of one laying season. Perhaps it's over thinking it, but did Eastman and/or Laird consider them full blooded brothers when they crafted the backstop in late 1983?
