Right now my 10(osh)week ISA brown has her own little pen, and my 7month Australorp and White Leghorn have their own big pen. They get to run around the backyard almost every night, and the last couple of days I've been letting them out together. The Leghorn ignores my baby, but the Australorp rushes over to peck her if she gets too close (3 or 4 metres is apparently 'too close'). I've been letting her have a peck or 2, and the ISA brown runs away, but any more than that and I've been stepping in to protect my baby. Am I being overprotective, or underprotective or just enough??
