I have one pen I call the "Dinner Theater" because I keep the young cockerels growing out for dinner in it. It's made from a trampoline too worn for bouncing, it still has the trampoline top and there's 2 X 2" wire all around the sides. There is closer-knit mesh around a quarter of the edge and that's where I placed long poles for roosts. It does a fairly good job of keeping them safe, but it's not thoroughly predator-proof. So I was anxious the other morning when I heard a great commotion coming from that pen. I feel especially bad when a chicken gets preyed upon in circumstances where I could/should have made safer for them. I ran out to the back paddock and see all these big cockerels running around & around their circular pen, squawking & shrieking. What could be in there causing them such panic? I was so surprised when I finally got close enough to see the culprit. He was small and white and chasing all the large cockerels around the pen. It looked like a pen of wild mustangs running around a corral with a short bronco buster cracking a whip after them. That bronco buster was... a little bantam rooster! He had every one of those large cockerels running away from him! If they slowed down at all he would run up to them squawking & pecking. I usually free-range these guys every day, when I opened the gate they all tried to get out at the same time, it looked like a scene from The Three Stooges. And then the little bantam sauntered out at the end all by himself. This is a little mixed-breed bantam that's special to us, we call him "Squeezy" because I actually saw his Mom squeeze out his egg. It was really funny to see, this little bantam hen named Finch was in a nest box one day and as I watched she would stand up almost vertically and make this high-pitched "EEEeee" sound as she strained to squeeze out the egg. She did this 4 or 5 times before the egg finally plopped out. I marked that egg & set it under the next broody hen I had. And "Squeezy" was the chick who hatched out. He's certainly worth his weight in entertainment value alone!
