After LOLing at videos of guineas doing the goofy head down, run backwards thing, I was outside and watched a RIR pulled do the same darn thing!!! She did it three times, some of the other chickens were around and she would just put her head down and RUN backwards until she hit something. What the heck???? I didn't know CHICKENS did this! I swear, I have crazy chickens.....it was mighty amusing though! She is healthy and happy, 16 weeks old.
