I'm sorry to hear that Mistari. You have my sympathies.
Since that day, Godzilla and Mothra have been coming home faithfully. I built a coop and run, and wanted them to try it out yesterday morning, but forgot and put them out as I always do. Last night I got home and Mothra had already made it home but no Godzilla, and the two are never apart. I went searching my neighbor's yard with my high beams and found him(her?) on the other side of the fence about three feet off the ground in a bush, happy as a clam.
Today, they spent their first full day in the coop and run, and I was rewarded with my first egg, about the size of a golf ball.
