my wyandotte hen has been acting a bit strange lately. we added some 2 month old easter egger chicks as company. Shes been solo until now due to an attack a couple months ago from a night predator. she will fly/jump/run to the chicks and will lower her head and make herself look slightly rounder and stare hard at them. after she stares she either will start to chase them or run back to where she came from, and mutter under her breath while doing that. she will also have this behavior for no apparent reason at all, like she will charge at nothing and lower her head and stare, and run back to where she came from. she also always keeps an eye out on them just in case they start pecking at her favorite plant or something and will charge over. for the most part the chicks are taking it well i think, they are a smart bunch and have already figured out an escape route from her if she chases them. i know her behavior has to do with her trying to make sense of the new chicks and their place, but what exactly is she doing and what does it mean? also are there any behaviors to watch out for from her or the chicks?
