Only have 3 chickens that lay eggs atm so right now it's pretty easy to differentiate with colour and shape. I am planning to get an Araucana rooster in 2027, so that should make things easier with the fancy blue and green colour of his offspring. Right now it's pretty casual data collection, So I don't really look at weather, feed change etc. I do note down specifically in relation to laying that eggs are being predated and when a chicken goes broody and for how long. And roosters/introductions is more management side which is also written down, but more so for the breeding projects. General stuff I do note down is birthdays/age, weight at specific date, deaths and which chickens are raised by which broody/me. That last one might impact behaviour and stuff like that.I kept an egg spreadsheet for a while. It's good for a lot of learning, like understanding the arc of the laying season.
If you want to track each bird's production, it'd be good to keep a close eye on eggs and learn who lays what. Color can vary enough to be confusing, but an individual's egg shape seems to vary less.
Also would be helpful to add a column for weather and another for impactful events (predator attacks, introductions of new birds, deaths, presence of a bully rooster or hen, change of feed, etc.) to account for the effects of stress on laying.
Personally, my favorite reason for egg data has been to calculate our cost-per-egg. It's >$12/dozen here. Actually, I should probably track and calculate that again now that most of our layers are 4 and 5 years old...next season. I keep too many spreadsheets as it is!
If I start calculating cost per egg I might as well stop with chickens since I don't really eat that many eggs. And the PFAS situation doesn't help. Here eggs should be between 2 to 4 euro per 10 eggs depending on if it is biological etc. But I will be looking at it that way from the meat side of things, so cost per kilo meat. Which is around 8 euro per kilo atm.
Since I only just started data colection this year I am worried there are better ways to note data down. I do plan to let statistics loose on the data and I really don't want to be fixing a whole year of data.
