Scientific & Biological Overview

Keeping chickens healthy and productive starts with good feed management. Tracking how much feed your birds eat compared to their growth and egg laying helps you catch coop drafts, feed waste, or seasonal laying dips early.

Frequently Asked Questions

What does Feed Conversion Ratio (FCR) mean in poultry?
FCR simply measures how many pounds of feed your chickens consume for every pound of body weight they gain. A lower number means more efficient, healthy growth.
Why did my hens suddenly lay fewer eggs this week?
Laying drops are most commonly caused by shorter autumn daylight hours, summer heatwaves, molting (feather shedding), sudden feed changes, or a predator frightening the flock at night.
How long does chicken egg incubation take?
Standard chicken eggs take exactly 21 days to incubate at 99.5°F (37.5°C), with lockdown and turning stopped on day 18.
