Hello, I purchased a 4 year old Black Angus bull here several months ago. The owner said that this bull does his breeding at night time. I have 15 open heifers currently running with him and have not seen him ride any of them yet. Although he does do a lot of sniffing. I have snuck out a few times at night but have never caught him in the act. I grew up around dairy cows and have never heard of such. So I'm wondering - have any of you ever had your black angus bull - do the breeding at night?
