Is the 'Id sacrifice valid if a defect appears in it after it has been designated?

Question : If these defects are found.

Answer : Yes. Without the action of a human being. After he designated it, meaning he said, "This is my 'Id sacrifice," and there was no transgression or negligence on his part or that of its owner, it is valid for him. If it was due to the action of a human being, he is liable for it, and if it was due to transgression or negligence by its owner, he is also liable for it.
The reason for this is that it is a trust in his hand. However, if these defects occur before he designates it, it is not permissible for him to designate it because it is not valid. Accordingly, if it becomes clearly lame before he designates it—he bought it as an 'Id sacrifice but did not designate it—then it breaks and becomes clearly lame, it is not valid. If he designates it, saying, "This is my 'Id sacrifice for me and my household," and then a defect that prevents its validity strikes it without any transgression, negligence, or human action on his part, it is valid for him. The reason is that it is a trust in his hand. Yes.
