It has been a very busy summer. I have learned a lot in the last two and a half months.
I am trying to learn and practice managed intensive grazing. The sheep made one and a half trips around the fields before the grass ran out. I was able to give the lower field some attention: a whole lot of lime, some minerals (iron, etc.) and some seed to fill in some of the blank spots. The middle and upper fields still need a lot of attention: this year all they got was a grazing and a good, through mowing.
The lower field has a small hill, most of which has very spotty clumps of grass and a little bit of clover. I overseeded with clover and orchard grass. I also got about a dozen 40 pound bags of compost. I spread these very thinly in the bare patches over the seed. I was hoping that the compost would help capture and retain a little bit of moisture and aid in germination. I was also wanting to add some organic matter to the soil (it is rather sandy/rocky in that area - we live in the "granite state" after all). It appears to have worked. For a couple of weeks after seeding, there was no germination. Then we (finally) got a few hours of rain and within a couple of days there was massive germination where the compost had been spread. In the other areas, there was some germination but probably only one percent as much. My next grass project with the middle and upper fields is to apply lime and overseed.
We moved the sheep every day or two. Each time, we set up electro net fence around the next paddock, flop the fence down between the old and new and the sheep hop to the fresh grass. Catherine worked on training the sheep to come to a shaken can of grain, and it worked (especially with the ewes) - any time the sheep got loose or we had to move them between fenced areas, we enticed them with grain. This is definitely lower stress than trying to herd them to the right place.
We have 42-inch fence, but we found that the Blueface Leicester has no problem hopping over it. One of the lamb ewes went for fresh grass on her own whenever we didn't move them soon enough. We also found that our engergizer is not strong enough. With just one section of fence, we had in excess of 5K volts (a good deterrent). With four sections of fence, we had 2.5K volts (not a very good deterrent) - I often saw the sheep grazing fresh grass through the fence! I bought a much stronger energizer a couple of weeks ago, but didn't get a chance to hook it up before we ran out of grass. I picked the strongest one the supplier sold (and the only one with which they are trying to upsell warning signs).
I have some ideas about how to ease the process of moving the sheep around the fields - I will discuss those another time.
As the grass was running out, I built a second permanent pen near the barn. We moved the ewes to the large pen and the rams to the small (new) pen. I am now in the process of building a combination sheep shed and chicken coop. The shed is adjacent to the large pen, and I will just take down a section of fence to provide access to the shed.
The sheep are now on hay. I am able to get hay in small volumes all winter from a nearby horse facility at $6.50 a bale (for now). This is cheaper than the local grain store ($7.25 a bale). It looks like they are eating about a bale per day. I am flushing the ewes with whole corn right now and plan to mate them in about three weeks.
