Hi Kinderchick,
If memory serves me, a Tuppernest was installed in 2011. At the time of installation they had laid four eggs, two of which were damaged, which TPC removed and two were put into the tuppernest. Both hatched that year but one did not survive 24 hours, the other was banded and named "Polo" (like Solo, because he was alone). I don't recall that the tuppernest was ever removed.
