You'll get no argument from me on those points.I wouldn't mock her but I find it slightly irritating that she would have people believe it seems she has discovered all these facts about chickens from spending six weeks with them.
I put links up to these two particular study summaries in the hope that people will read not just the summary, but also follow the links to the original studies.
Science has known chickens are intelligent creatures for many years now. Old School Chicken keeping enthusiasts could have and maybe did broadcast this news long before the behaviour studies became more common reading.
If you haven't already take some time out to read the papers.
This is an old paper 2012.

Each time a study on other creature intelligence gets done, it becomes apparent that it isn't the subject's intelligence we are testing but our own lack of it in many cases to devise the experiments and set up the conditions to attempt to measure these creatures intelligence relative to the world they encounter. We measure for example their ability to count because some of us can do that. More difficult but far more revealing is their ability to recognise individuals in a group and the information they may use to make such recognitions.
The problem of flight, even at chicken competance level requires a vast amount of calculation which we, humans, cannot manage and cant even get the best computer fight navigation systems to manage to achieve the manouvers many birds can.
