Mr. Valentino has twice as many ducks as chicken on his farm, which means there are 2*200 = <<2*200=400>>400 ducks on the farm.
The number of turkeys is three times as many as the number of ducks on Mr. Valentino's farm, a total of 3*400 = <<3*400=1200>>1200 turkeys.
In total, Mr. Valentino has 1200+400 = <<1200+400=1600>>1600 ducks and turkeys on his farm.
If you add the number of chickens on the farm, the number of birds on the farm becomes 1600+200 = <<1600+200=1800>>1800 birds.
