Mine fell apart

I am going to play some. I wonder why mine spread and got thin but fell apart?
Any ideas? They tasted super though...

I wonder if I added a bit of carbquick if that wuld help?? I could ditch the baking soda too. I ordered some and it should be here in a few days...

I had a bit of dough left so I played some and added more egg and a touch of protien powder and these seem to be staying round..
