Hi newbie with silly question...I have a 5 EE chicks about 5 weeks old.. They are suppose to be pullets, however yesterday when holding them I noticed than one has tiny little nubs (bumps) starting to form where I think spurs grow. Does this mean she's a he? or do pullets get these too? None of the others have these..so I'm thinking she's a he..just wanted to check before I re-home. Thanks in advance.
