How the hell does one kill 2 MILLION hens?
I was going to ask the same question!
Ever talk to anyone who works for APHIS? We don't monkey around with avian influenza or 101 other animal diseases. APHIS is perfectly prepared to kill every cow in Iowa if that's what it takes to contain an outbreak of hoof and mouth disease. They will kill the infected animals and potentially infected animals immediately and settle up with the farmers later.
I think we should put APHIS in charge of the border. That could solve a lot of problems.
Shut down ventilation and heat up the building. Sometimes pump in CO2 or firefighting foam.
