I breed all year round, watching your females is very important to do it this way as well, you can miss an opportunity if the female is ready, so pay close attention to how your females are acting and what they are doing (cool seeking, feeding habits, etc). I typically have 3 set "seasons" in a year, I start my Oct girls, Feb girls, and then July girls. Although, this year my Oct girls didn't seem to want to take until March and I got hit with a ton of ovulations in a very short period of time.
