How do I return the date in which the column records the first date in which the column “chicken” has a value of “1”?

I have a data set in which IDs are repeated for each date that a meal is eaten and the type of meat that is consumed is recorded in separate columns. How do I return, in a separate column, the date in which the column “chicken” is first recorded as a “1” for each ID?
