Fun thread! 
I can’t think of any myths that haven’t been covered already. 
My roosters crow whenever… though I sleep through it, so I thought they only crowed during the day until my hubby & kids slept in hammocks in the shed which is about 2” away from the coop. Turns out they crow starting at 3am! 
Several of my chickens could “fly.” They didn’t take off and go south for the winter or even make it up into the trees to roost (though I’ve heard of bantams that can). Mine could get over the five foot tall fence even with one or both wings clipped. Since the hawk attack in oct 2020, we have fencing on the top of both runs, putting an end to flying out of the pen… they still like to run and fly around each morning when they think I’m coming with treats! 
I get blue, green, cream, tan, purple, brown, speckled, dark brown, & white eggs from my girls. The blue & green ones are blue on the inside. The rest are white inside. My Maran has the pinkish bloom over the dark brown eggs more so at the beginning of each laying cycle thus the purple eggs. 
Roosters aren’t needed for eggs, of course. My one neighbor refuses eggs from us. She once cracked a chick out into her skillet and now swears off backyard eggs completely. That egg did not come from us as she’s never taken any from me. No amount of reassuring her that I collect eggs daily & therefore they can’t develop into embryos at all (unless she would put them in an incubator) will convince her to try again. 
I’m not sure about ACV for animals (though I do use it as well as copper sulfate, and I also use antibiotic prescription meds, Denagard, Corid, etc when needed), but I will stand behind saying that ACV with the mother (homemade or Bragg’s brand) 

 percent of the time cures my stomach pains!! I’ve had gastritis five times (diagnosed by an upper gi the first time) and random heartburn or reflux as well. It cures them all. I take 1 tablespoon in a cup of warm water with a little honey to make it taster. Plus honey is anti microbial too (it lasts for thousands of years like in the pharaoh’s tombs)! 
I think my chickens are smart. Not as smart as my outdoor bunny or outside kitties all of whom are potty trained. Sigh. I wish the chickens could be potty trained. Even my horse pooped & peed out & under her stall door during the weeks she was boarded for training.
