First locks are exciting! We just had ours a couple days ago with a Genetic Banded X Normal. This morning we woke up to find our second with our Graziani Pastel X Normal Pairing. This one surprised us as we didn't think he would this year as he is just under 500 grams and 07 born. We had been trying him for a while now with no success. I guess since they are in the same room he may have somehow sensed the banded locking up and decided it was finally time to get busy!
