Newbie question here--I'm waiting to start vaccinating yearly. I hit the calves with blackleg now, but they aren't too bad to deal with. I do it when they are still too small to kill me--I need to figure out how to handle the cows. I have a catch pen, it is two pens connected with a lane on one side that they can go out. This lane is narrow obviously--its the only spot I have to get one confined. I have a head catch but I don't trust it--it is old and real light duty. Is getting a cow in a lane one at a time a reasonable way to attempt to vaccinate? I'm looking at this from a safety for me and the cow standpoint--no real injury is possible for the cow that I can see. I could potentially administer the shots from above the cows--does anyone use this kind of setup? Is it even possible to vaccinate cattle without a real squeeze chute?
