I too have never lost a pearl to a predator but lavender & anything pied gets snatched up! The white sure are pretty. I am doing a coop just for the light color keets & not going to let them out to free range. I will see how it goes!
Mean to who? You or the other guineas? All male guineas chase each other around like they're going to kill each other...especially in the spring and summer breeding season, but the rest of the time mine are fine with each other.
