R' Meir says: Any work which one began before the fourteenth, he may finish on the fourteenth; but he may not begin it initially on the fourteenth, even if he can finish it [before midday].  But the Sages say: [Practitioners of] three crafts may work on the eve of Pesach until midday; they are tailors, barbers, and launderers.  R' Yose bar Yehudah says: Also shoemakers.

We may set up coops for chickens on the fourteenth.  [If] a [brooding] hen escaped, we may return her to her place; if she died, we may set another in her stead.  We may sweep away from under an animal's feet on the fourteenth, but on the festival we may [only] clear it away to the sides [of the stall].  We may take utensils to, and bring them [back] from, the house of a craftsman, even though they are not needed for the festival.
