Always good indeed to note all things, we had a female here last year who had a small ovulation (and only 3 eggs, no slugs).
Eventually you will start to notice things and the pattern of you animals, silly example I took my fire female out yesterday and noticed she was building. Looked up my notes and she ovulated end of february in 2017, so just threw the male in there and had a solid lock in one hour. So should be all good
Sometimes males are silly, I got a Bamboo Fire (son of the fire) who has sperm plugs and everything... but for some reason the kid is not really getting it just yet lol![]()
