Thanks for sharing that. I love when these little things get mentioned that aren't on all the caresheets.
One time when my girl shed I was scared she had somehow ripped her spurs off in the shedding process. Then I looked closer and there were still spurs there, but just much smaller than before the shed. So she must have had a few layers built up but just got them off that shed. Glad to know she isn't the only one that does that.
Getting back to the OP, I've often heard that the size of spurs is not a good indicator of sex. So I'd believe the results of the probing.
