This is just the sort of information I was looking for this evening, but I'd like to ask a couple more questions, just to tweak what we were thinking of doing. We have real winters here, so fly control late fall through mid-spring isn't an issue.
Our cattle are on pasture now, so they don't need to come in for feed. We can keep the feed/water areas separate, but close. They DO need to come in from pasture for water and salt. We currently have 8 head; none that have or are new babies (some due later, early fall). To deal with water and salt access only, would a 16 X 16 corral, or 16 X 14, or 16 X 24 work (we have panels to do any of those combinations), with two 4-ft. in/out access spaces, so they can get in/out with blocking . . . using the diesel and chemical rags over the gates ?? That seems to me to be effective, without the expense of re-filling dust bags.
Second question, what do you use for the rag material -- just anything, or a medium weight canvass, or ???
And finally, what's the optimum height for dangling rags -- a foot below shoulder level? or, more? less?
Appreciate your thoughts/ideas.
