Colpitts Oscillator schematic to breadboard implementation
All the holes a,b,c,d,e in a row are connected together. All the holes f,g,h,i,j in a row are connected together.

So if we look at rows 4, 11, and 15 in your image, we can see that the capacitors are short-circuited.

You need to do the layout again bearing in mind which holes are already connected.
