Buck rag

Sooo when I had two bucks both were in rut peeing all over themselves and going crazy over the ladies we’ll I sold one buck like a month or two ago and the buck I have has no interest in the girls. So my question will a buck rag bring him back into rut?? If so where can I get one??

I preg tested my ladies that had CIDRS and he only bred one of the 3 he had. I haven’t seen heats but I think it’s because he’s not good and stinky.
