Right now my flock consists of a barred rock pullet and an austrlorp both 9 months old. I had some losses but now I'm working on building my flock. Today I just got 2 baby chick Australorps from a local feedstore.
First question : If I decide to stick them under my pullet, do I first need to quarantine the chicks and for how long?
My other question is about my Austrlorp pullet. Lately she has been puffing up and fanning out her tail when I come close. She does this while walking around--she hasn't started just sitting in her nest although I've stopped collecting the eggs for a few days to encourage her to go broody. She is the sweetest girl and very shy, so I definitely don't think it's an aggressive behavior because she will still let me pick her up and sit in my lap. Also, I have seen HUGE poops in their area so... Is she on the verge of going broody or just a weirdo?
