i just went out to inspect our small flock, and after picking one of my girls up i realized her belly is missing a ton of feathers! some have been broken off, but the majority have been completely plucked. i inspected her closely for mites/lice and found nothing (however this is our first go with chickens, so i don't really know what to look for). she's not even a year old, is that too early to go broody? she doesn't seem to hang in the nesting boxes more than usual, but i haven't really been paying that close attention. what are some other signs i can look for? does it sound like a broody or should i be more concerned? thanks in advance!
