I guess the first question I wouold ask is, define a breeding scrape for me.
I fooled around with scrapes for about 20-years. I made mock scrapes and usually started them during the spring turkey season. I use nothing but my own urine and if I picked the location correctly and had the right overhanging branches, about 50% of these would be "picked up". To some extent, these scrapes were used all year long. I freshened them every time I walked by and activity naturally would increase as the peak of the rut approached and then wane as the rut was completed. However, other than that, I could see absolutely no evidence of a connection between a scrape and breeding.Some scrapes continued to be "worked" all year as long as I whizzed in them now and then and I have never had any desire to breed a deer.
They are a tremendous communication tool for deer. Scrapes, just about any of them, are used by different bucks and does of all ages. However, not for the purpose of breeding. Long misuderstood, the scrape was thought to be how receptive does and eager bucks, "hooked up". Balderdash! Nothing of the sort.
Scrapes can appear at any time and be used at any time with the peak usage coming as the rut approaches but does not reach the peak. The reason being, that is when the most traveling and communicating occurs. Just to confuse things, 85% of all scraping activity occurs at night. But of the greatest interest to me, is that scrapes just 75-100 yards apart may be used by totally different bucks. I haven't figured that one out yet. But I can tell you one thing you can bank on. The size of a scrape has nothing to do with the size of the bucks working it. Foour small bucks can make on heck of a scrape.
