So, lets start this off with a little story. I sell chicks. Lots of chicks. Most of my buyers are very polite, tell me I have some cute chicks (usually accompanied with an "awww...hunny, get me that one!") This last sale was different. First, the buyer lied to me about how much silkies were selling for at a local feed store (trying to get me to sell mine to her cheaper). Then, the buyer got lost on the way to look at my chicks (which usually isn't a big deal). She said "I'm on ___ rd"..Me: "I'm sorry, I don't know where that is, but it does sound like you got off the interstate too early"...Buyer: "How long have you lived here?"...Me: "About six months"...Buyer: "Oh well, you should know about ___ rd. You've been here long enough!"...normally, that wouldn't bother me, but the buyer was just so snotty. So, eventually the buyer shows up and we are now looking at the chicks. The buyer picks one up. Pets it's head.. Then flips it over. The buyer has the chick's feet inbetween two fingers and the chick is now flailing about upside down. The chick begins to peck the buyer's hand. "This is a rooster. I only want hens," the buyer says. The buyer proceeds to tell me that due to an equilibreum (excuse the spelling) problem in roosters, when flipped upside down, the rooster will begin to peck and try to get right side up again. If it's a hen, it will stay calm and just hang upside down. Of course, I was slightly horrified at first, but I didn't really know what to say. I also couldn't be like "YOURE WRONG"...because I had never heard of that before. On top of being scared for my chicks everytime she flipped it upside down, she couldn't stop cussing, evaluating the quality of my chicks, and just...acting downright rude!! SO! Onto what I really want to know... Does that sexing method actually work or did I just have a really rude buyer that I should avoid in the future at all costs (haha)?
