I don't see why some folks are getting all exercised about the study
itself. We don't even know hardly anything
about it, as the study does not seem to have been published yet; however, from what info
is given, it seems extremely unlikely to ACTUALLY mean what many people here and in the media are claiming it does, anyhow!
A one hormone (in eggs, at that!) measure is not a very satisfactory measure of anything's overall well-adjustedness. But MORE IMPORTANTLY, if you look at what the p.r. does and doesn't say, it seems that the study only looked at *industrial* methods of chicken husbandry. Large scale industrial so-called free-ranging has as much to do with what people on this forum do as a marshmallow Easter 'peep' has to do with an actual live chick :> For heavens' sakes, without seeing the actual research paper we don't even know how comprehensively the work should apply to the range
of commercial 'free-range' practices that exist out there!
The problem here is a) the public announcement of a conclusion w/o accompanying release of study information, which is regrettably not uncommon these days but which should be campaigned against; and b) some almost certainly unwarranted conclusions that are being touted as fact.
I am sorry to sound cranky, but having been a biologist for a number of years before moving up here and getting married and having belated kids (and having been, back when I had a career, just as cranky about this sort of thing with my students
), I just have to say this:
---
Don't take things you hear at face value, especially if they seem surprising.
---Take a minute to look at as much of the original source as you can find. Google (etc) is your friend
See what is
really being reported as well as the methods by which that information was obtained.
---Distinguish between facts (e.g. 'chickens from condition A showed x average amount of whatever; chickens from condition B showed y amount'), which cannot generally be argued with, versus the researcher's own interpretations/conclusions (''thus chickens experience no more stress in cages than free') versus further wild extrapolations in the media.
---Then, now that you know more about the 'facts' and the methods by which they were obtained, you can decide for yourself how much of the interpretations, conclusions and extrapolations seem to be justified.
Running around in a swivet with hands in the air over media reports is NOT helpful -- not to people themselves, and not to the larger goal of getting people to quit releasing misleading or incomplete information in this way in the first place.
Sitting down and shutting up now,
