Ok, I've got eggs pipping right now and need to occupy myself so I am going to share with y'all how I made my egg candler. It works extremely well. I have 2 size attachments. One is for chicken eggs and one is for goose eggs but you can make it to any size. What I used: $10 flashlight from wal-greens. Its the 17-LED and its great because it has a bright light with low heat. childrens foam blocks. You can see mine are pre-loved (chewed) LOL... but whatever works. cardboard tape exacto knife or box cutter Here are the blocks that I have that fit perfectly. They are soft foam. http://www.amazon.com/gp/redirect.h...bgcom-20&linkCode=ur2&camp=1789&creative=9325 Here they are at toysrus. I think they now come in that wood grain look but mine are several years old. http://www.toysrus.com/product/index.jsp?productId=3207529 Ok, now here is my flashlight and blocks Now, this is so easy. Just stick your flashlight into the hole Now you have a goose-egg candler To make a chicken egg candler, take a small piece of cardboard and cut out the size of the square block. Now take a coin (I think I used a quarter or nickel, can't remember) and use the coin to trace a circle in the center of the cardboard square. Then cut it out with the exacto knife or box cutter and tape it onto one side of the block. Then stick your flashlight in the other end. Now your candler is ready for a chicken size egg. You can do the same thing using a smaller coin like a dime or penny to candle bantem, quail or small eggs. Here is my chicken-egg size candler. I recycled a purple cardboard from a fan box which is why it matches my block and says fan on it. (don't mind my messy desk!) Ok, hope you enjoyed this method of making a candler. It works very well because the blocks are soft so its gentle on the eggs and it also hugs the flashlight so snugly that no light is lost out the sides. If you can't reason spending the money on these blocks for this purpose, just keep in mind you might have a toddler somewhere in the family to give the rest of the blocks to at christmas time.
