I gave up blowing out eggs with anything but a syringe years ago. Makes my cheeks hurt alot less that way. I get mine at the local farm store like Mojo Chicken said.
I make my holes with a thumb tack or push pin. The plastic ones. I never make a hole at the bottom and it makes it a little harder to get all the stuff out but one less hole to bother with later. Had a few pop in my hand a until I learned how much pressure the egg could take.
I love all the pictures on here. They are so pretty and I never thought I could make something so pretty but now it seems possible after reading how to do it on here.
