I suppose with feed costs etc. that's entirely possible. My situation is different where we have an abundance of feed and grain. We're down to only 80 head of cattle from 140, but on our way up again to 100+ head. So we grow our own grains/hay etc AND HAVE THAT advantage. I'm hoping to increase the 7 ewes I have right now to 40 in the next 3-4 years.
I was just talking to some premise id people on the weekend. I have a link for the tags from the main office in Alberta. I'll look it up and post it later.
You may be able to order tags from the sheep development board in Saskatoon. I'm not sure about goats, but sheep have a checkoff fee (when you sell your lambs to a buyer/auction mart) that goes to the sheep development board. If you have questions about sheep and/or goats...they should be able to give you more information. That's what they're there for. Gordon Schroeder is pretty good for information.

Some information on the tagging programs. I'm not familiar with the goat one at all.

And the CLRC is the body who looks after the pedigrees for most of the breeds of Canadian animals

I'm not sure if there's more on goats, I'm not as familiar with them.
