Goats aren't dropping horns for me in the caves and cliffs experimental mode

I've tried many times, I made a goat charge into a solid block. I have tried two blocks four blocks but they never drop a horn. I am on the caves and cliffs experimental mode and it never works. I've tried placing a block before one hits me and that didn't work. I've tried dodging the goat so it rams into a nearby block and that didn't work either. Pls help me figure out what's wrong
