Im not sure when mine started, i bought the older ones in March and April last year. My toulouse were only 7 mos old at the time and im still waiting for them to show interest in breeding. The guy i bought the chinese and romans from said that the chinese started laying in december and the others in january but i think he was just BSing me. I have heard that bubble wrap along with packing peanuts and some saw dust is a good way to ship the combo is supposed to work well together in stablizing the eggs and doesnt let them shift. So im going to try that.
