Growth charts are really only any good for table birds, when you want to calculate the conversion rate of food to weight etc.
I know some people make egg charts, however if all your hens lay similar size/shape/colour eggs then it will be difficult to keep a chart of the egg laying for each hen. though you could simplify it to 1 egg today, 3 eggs today 2 eggs today etc, if that would satisfy your record keeping
At the moment I have a hatching egg spread sheet ongoing, eg.g source, cost, breed, colour, cockerel, what day they were set, how many were viable, hatch date... and for the future, leg ring number and sex.
