Humane? An Enriched Cage is Still a Cage
The American Humane Association’s (AHA) farm animal welfare certification program – American Humane Certified – announced in June that it will permit the use of so-called enriched battery cages for laying hens as an option for humane housing. Humane? My first reaction on hearing this was, “Hey guys, you do realize this is still a cage, don’t you?” But let’s be evenhanded about this and look at the reasoning put forward by the American Humane Association. The American Humane Association’s rationale for this decision is that these cages are “enriched” to allow hens to exhibit natural behaviors. In making this decision AHA states that it has carried out an extensive scientific review of the behavior and welfare of laying hens housed in such systems – mainly looking at research from Europe where conventional cages are soon to be totally banned. Okay, so I might consider accepting that an “enriched” battery cage possibly offers better welfare opportunities than a standard battery cage. But AHA fails to recognize some key behavioral needs that hens are driven to perform. I am talking about providing the birds with space to run, stretch, flap their wings, and fly; litter and somewhere to dust bathe; and vegetated areas to peck at and forage in. AHA also significantly underestimates the ability of enriched cages to provide adequate nesting and perching. So what does the research really tell us about “enriched” battery cages? And are they really a humane option? I was pretty confident that a lot of research existed to say some of these behaviors are not wants but programmed driven behavioral needs.
