Thanks GaryDean....It would be really neat to have a registry. It sounds like a lot of work though. I don't think that we would get a lot of peole to put the time into a registry. Farm records are propablly still the best way to go. If you put up a page other could track the same information to make our farm records more unitform. (i.e. Weeks to first egg, egg weight, annual production, etc. are things others might track).
I usually don't candle until day 18, so yes clear eggs are eggs that never started. Either from not being fertile or the embryo dying during shipping or other egg handling prior to incubation. Yes, the red ring are the early quitters and yes the developed embryos that die later on are the late quitters.
Since I see we can make tables in member pages.... I will give it a shot and see if the columns and rows make sense. A table where others could replicate the page...may be possible, then it would just be fill-in-the-blanks for the ones who want to share records about - age at first egg, weight etc. Any other things anyone else wants to see tracked on each bird or family of birds...drop your ideas off here.
