Pox parties are nothing new*, but generally the reasoning behind that is to let children catch a very curable disease before they’re older (a teen or adult) and it’s harder for the immune system to overcome.
Is this the same reasoning behind letting a large group of birds catch pox all at once? I don’t understand why you would purposely introduce that at all?
*for the record, pox parties are generally organized in this day and age by closeminded anti-vaccinators and are often bordering on illegal. This isn’t the 1800’s, no one’s child should be dying from measles with modern medicine available.
Preach sista! (Referring to the measles comment)
