Older children could become quite skillful with the features of the new Graphics Editor (Copy, Paste, Delete, Eraser, Layers, Grouping, Ungrouping) and the way they work across costumes and sprites. Here I have combined elements of the egg sprite with elements of the chicken sprite. Then it's a case of trying to get the algorithm right. I would add that I'd personally find the graphics of this project very difficult on a tablet. My lack of precision with the tools without a mouse at mu disposal would be asking too much of me.
All the graphics are available in Scratch 3. Chicken sound courtesy of soundfx.co.uk
