egg-laying competition

Three chickens had egg-laying competition. The competition lasted several days. The one who laid the heaviest egg on that day got the highest points. The one who laid the second to the heaviest one got a little less points. The one who laid the lightest one got the least points. After several days, chicken A got 22 points, and chickens B and C tied together with chicken B being 9 points. chicken B laid the heaviest egg on the second day. Which chicken laid the heaviest egg on the fourth day?
