This is the first I've ever heard of a roster mounting a chickin, and I don't even know what that would look like. However, a rooster can mount a chicken for only a few seconds and get his work done.
It's quick. They call it "topping".
A matter of a second or so. It's "slam, bam, thank you ma'am".
How long does a roster take to sperm when mounting a chick in
