I have a happy and healthy flock of 9 beautiful birds. I have 3 Bantam chooks, who tend to stick around together, and 6 Isa Browns. Lately, I've been noticing that one of my Isa Browns, Zarli, has been going off on her own and doesn't seem to be bonding with the rest of the flock very well. The Isa browns are only 22 weeks old and I've had them about 6 weeks. I suppose it's silly but it breaks my heart when I see her alone. Is this an indication that something is wrong? There is no violence or fighting in the flock, which I'm grateful for, I'm just worried for my lonely chook.
