Yes, it is! I have a notebook on each pen where I record fertility (egg count % based on candling), hatch rates (male/female and actual number that were successful), health and vigor of the birds in each pen, reasons for culling, and pictures of each breeder for that pen with a description of strengths and weaknesses according to the SOP. I also keep a diary of weather conditions which correlate with the impact on the individual pen records.
My sister's family is involved in genome research (Hunkapiller) so there have been long discussions on research and record keeping. ...but that's part of the fun for me...call me anal or crazy.
As long as you are having fun....that's all that really counts.
