Whisk together the egg whites, lemon juice, colouring and 100g of the Siúcra/McKinney's Granulated Sugar until thick using an electric whisk.
Fold the remaining sugar into the mixture. Place the mixture in a piping bag and pipe small chickens onto a greased and floured baking sheet.
Bake in the centre of the oven at 125°C for about 1 hour. Using the icing, add eyes and beaks to the baked chickens.
