I must say that I spent two hours reading about chickens. Some of which was disturbing, especially the rescues done in battery farms. This reading all started with the link I posted earlier about the intelligence of chickens. Okay, some argue the study was biased, but I was under the misconception that chickens were, well, just chickens. That is, of course, until Myrtle and Harriet undertook to teach me otherwise.
I don't know that they could master simple arithmetic but I was surprised to learn that chickens do have a broad color spectrum. I've asked the DH to bring some physics diagrams next time he drops by to see the girls. I didn't know humans and chickens share 60% of the same DNA. And, that it is through genetic engineering that chickens lay so many eggs. I thought that was part of what made a chicken, well, a chicken. And yes, Eggna, Harriet, and Myrtle seem to know their names.
