50 turns to free 20 birds in this 4-grid level. The gifts and the birds will spawn in the bottom grids where the teleporters will transfer both of them in the grids above. The grids are diagonally connected so the bottom left will teleport objects to the top right and the bottom right to the top left.

The Iron Blockers at the bottom of the top grids entirely block off the keys to save the birds. The circulation of gifts also suffers so destroying them should be one of the first priorities. Don’t be afraid to use some of the boosters you have at your disposal as the flow of the grids may form some impossible situations. 

50 turns may seem like a lot but keep in mind that each of the Iron Blockers has 3 additional layers of iron on them. The opportunities for combos will be plentiful so use them as much as you can.
