We got 27 chicks from McMurray about 3 weeks ago. A combo of Silver Laced Wyandottes and Aruacanas. All of the girls are very curious and friendly, and we have been working on handling them. None of them peck at us except for one of the Wyandottes. She dosnt peck at the other birds, just at us humans. Any tips on how I can get her to stop? Thanx much!
