Poshite Yid 613- Did you read Jothar’s post on this page?
Also, there’s no one checking the chalaf that it’s smooth every few minutes; no one checking the chickens for kashrus (soaking,salting,rinsing,etc.), and no one checking to see if there’s something wrong with the chicken that would render it a treifa.
You would not buy this chicken for yourself under these conditions.
If you insist on using a chicken; use a frozen one with a good hechsher.
