Dany has to have 4 x 2 = <<4*2=8>>8 bushels a day for the cows.
He has to have 3 x 2 = <<3*2=6>>6 bushels a day for the sheep.
And he also has to have 7 x 3 = <<7*3=21>>21 bushels a day for the chickens.
Therefore, Dany has to have 8 + 6 + 21 = <<8+6+21=35>>35 bushels to suffice the animals for a day.
