Just for kicks and giggles I made an incubator from an old cooler I had. It was a small cooler and when I finished putting it all together, it only held 4 eggs. I had most of the necessary parts and only have like 10 bucks invested in it. I made a slide from cpvc pipe to push and pull the eggs so they would turn. I got 4 eggs from a friend of mine and gave it a whirl. He didnt even know if they were fertile or not but they were free so...Today is day 19 and I have 2 that have started pipping tonight. I have done everthing as I have read maybe all will be healthy...Time will tell..
