Hello ChicksHow to work out feed cost per egg
Short answer: Feed cost per egg = (feed used × price per kg) ÷ saleable eggs in the same period. Use the same dates for feed and eggs.
The formula
Feed is the biggest running cost on a layer farm, so feed cost per egg is a useful number to watch. Take the feed used in a period, multiply by the price you paid per kg, and divide by the saleable eggs from the same period.
Example: over 7 days a flock eats 5,600 kg of feed at ₹30 per kg, which is ₹168,000. It produces 28,000 saleable eggs. ₹168,000 ÷ 28,000 = ₹6.00 per egg.
Use feed used, not feed bought
Feed you buy goes into a store first. Cost per egg should use what was actually fed, so count what you issued to the sheds, or opening stock plus purchases minus closing stock.
If you changed feed brands or lots, use the price of each lot for the kilos used from it.
When records are missing
If you skipped feed entries for some days, the result is not reliable. A low number caused by missing feed records looks like good news, but it is not. State the days that are missing, or leave them out of both the feed and egg totals.
This is only the feed part. Medicine, labour, electricity and depreciation also cost money, so feed cost per egg is a measure of one cost, not profit.
How Hello Chicks helps
Hello Chicks uses your feed issue and stock records to show feed cost per saleable egg, and it shows how complete the records were. When something is missing it lowers its confidence instead of showing a precise-looking number.
