PC1 show that #exploration w/ age 🐣 w/ temperature 🌡️ (in Spring) was ≈ in and (PC2 showed ≈ tendencies) Characterisation of broiler range use with reliable & repeatable indicators will improve range use in #freerangefarming 5/6

PCAs of those 5 measures were very ≈ between lines. PC1 varied with time spent outside & movements around the field ; PC2 varied with how muchcovered the field 4/6

From those real-time location, we describe 5 measures of daily range use, all repeatable 3/6
