Think women are cruel? Try being a rooster.
According to a recent study from researchers at Oxford University, hens can actually expel sperm after sex. The researchers call the behavior “sperm dumping” and it’s as harsh as it sounds.
Hens are rather promiscuous. Even though they mate with many roosters, not all their mates are desirable. The Oxford researchers found that the hens were more likely to eject the semen from a low-status male. Hen pickiness didn’t stop there. They also were more likely to eject semen that came from roosters who provided especially big or small…loads.
