I have 13 eggs in my home made incubator. They are on day 7 right now. The temp has been really steady and so has the humidity. I just really want to candle them to see if anything is forming. Do you know any brands or types of candlers or how to home make a good one to see through these darker eggs. I have one egg that is ligher in color and it is labled "number 12" and I candled it and can see good viable viens and a nice big eye.... but I dont want to just keep candling number 12 over and over.... I'd like to see if the other eggs that are darker have babies in them! did I mention I got these eggs on eBay?! heheheh
