My blue

[TALKMYCHICKS]

I have a four week old Iowa blue, not quite all the way feathered yet, and I have a 5 week old Americana... this one is fully feathered, I bout them both at the same time.. both should be F... been introducing them to my roo and my other two, my roo has no problem with the fully feathered Americana but tries to attack my almost feathered Iowa blue... is this because shes not all the way feathered ???... I hope the will get along.
