Except for the availability of grazing new grass, fall calving is subject to the same decision process as spring calving. If you'll calve inside and have adequate high quality forage about any month would work. If you're going to calve outside, the earlier in the fall the better, less concern with some really ugly weather interfering. What time frame is the slackest in regards to toher commitments. Then too, it dependson what you consider fall.
We'll be goign to a small scale fall calving next year and we're shooting for october. Some folks calve in September but it's generally still too hot around here then. I also new bron calves hopping aorund in decmeber and january. That may not be too cold for the calves but it's definitly too cold for me to possibly have a problem and go out in that kind of weather. I'm just your basic sissy when it comes to cold
