I have a pied and an albino who I think are doing "stealth locks". The pied hardly seemed to lock with my pastel last year, and POP! Six fertile eggs this autumn. Okay, then.

But I'm fairly convinced that same pied genuinely doesn't like my black pastel female. When I switched their partners, I immediately saw locks from both pairs. I don't know. These small males are pretty hit or miss with their locks. Everyone says under 1000 grams is better, but it's my big boys who are the real Casanovas.
