Got a batch of chicks yesterday from tractor supply - they couldn't be more than a week old or so (mostly fuzzy but 2 or 3 itty bitty feathers coming in on the wings.) One of them, always the same one, has been letting out a piercingly loud series of cheeps every 5-10 minutes since dawn. The others are just peacefully cheeping at the usual decibel level. The TSC clerk didn't know if they were all pullets or straight run in the bin (it wasn't marked) and it's way too early to look for combs and other roo signs. It's a black Australorp - when I search on BYC for sexing tips I'm finding posts that say they can't be sexed til fairly far along. So is it a roolet or just noisy?
