Q. Someone bought a live chicken from a farmer, after doing kapores for his family he was to take the chicken to a friend who is a shoichet, but he had to make a stop on the way. He got busy with something else and forgot about the chicken on the back of the car. When he returned, he realized that the poor animal had perished probably from heath stroke, as it was extremely hot in the car. Does he have to repeat kapores. Should he then give the dead chicken to a poor goy? If you are yotzeh kapores with a dead fish why can you not be yotze with a dead chicken?

A. Horav Shlomo Miller Shlit’a pointed out that Poskim disagree if after shechita the fowl turned out to be a treifa. Some require to repeat kappores (Pekudas Elozor 604, K’tzei Hamatteh ibid. 12, see also Shulchan Shlomo 1). Others (Eishel Avrohom 2: 605, Knaf Renonoh 57, et. al.) are lenient after the fact. However, when the animal was not shechted properly and it became a neveila, all agree that one did not comply (Alef Hamagen 605: 1o, Nitei Gavriel – Yom Hakipurim 13: 4).
The Rov added that he is to blame also for the unnecessary suffering of the animal, and should repent on that too. The chicken should be given to a Gentile acquaintance or friend he owes a favor to, or be used as dog food.
