I introduced an 8 week old polish hen and two 4 week(maybe 3 weeks idk) old silkies to my flock today. They were quarantined together and every time one of my buffs got close to the babies my polish would freak out and attack. My buffs are all 8 weeks old too and were kind of scared so they left her and the babies alone for the most part. Anyways she was extra protective of them and I was grateful. is this normal at such a young age? She is only 8 weeks. And is this going to impede the acceptance of the flock towards her and the chicks or is this a good thing?
