About two to four weeks before the sheep are due to lamb is when I give them their CDT shots. This will give the lambs some immunity until they are old enough to get a booster.
I also use this time to trim hooves and give everyone a bit of probiotics. The coffee is critical to the entire evolution. The brown paper bag holds epinephrin in case one of the sheep have a reaction to the shot.
I usually try to give the shot in the loose skin just behind one of the front forelegs. Once the needle is inserted I always pull back a bit on the plunger for the syringe to see if I draw blood. Blood means I have hit a vein, very bad for an injection. If I don’t draw blood I continue with the injection. Make sure that the needle doesn’t go in and puncture out through the skin further on, this is caused by long needles or not being able to see due to too much wool.
The sheep are easy to catch but hard to hold, especially the Icelandics. The Cascades are so much easier to handle – sheep sized right!
