They're averaging 4-7 days per section, based partly on the condition of the grass, and partly on the weather. I've left them an extra day, or moved them a day or two early because rain was forecast.
I haven't gotten brave enough to cut them off from the pasture yet. They have a walkway back at all times, and then we close the gate overnight to lock them in- except once. One night #4 forgot to close the gate when he put them away, but still shut off the electric fence. They were out grazing in the morning, and may have been out all night. Amazingly, no escapes!
We still haven't got the second solar charger repaired, so the pasture is still not divided. It's obviously not as stressed as it usually is though. The grass is growing slowly, about 3" high. Normally it's cropped off just above the roots in the open sections by this time of year.
Friday I moved the fence to the first clearing behind the house. It's a bigger section than they've had to date, and the grass is longer, though thinner. The cows are all looking lovely.
I have one more section that I can fence off and maintain the pathway to the pasture without buying more supplies.
The horses come out to graze from time to time, though they're a bit skittish through the pathways where the fence is narrower, and seem to prefer the openness of the pasture. They're also adverse to change. They tend to leap before they look, and skid to a stop when they see the fence line has been moved.
The last time we tried using electric fence out back was just for horses, and it was a total fail. They always wanted the grass on the other side of the fence, would knock it down or ground it out, and escaped regularly. Now that I see the behavior differences I'd really like to separate the pasture to keep them in at all times.
