hi there. just get started off saying that i love this site. i researched all different kind of stuff on here before i bought my chicks. my chicks are now respectively 5 weeks old and the baby is 4 weeks. we lost one of our originals at a week old and they seemed to have accepted a new one. 3 buffs buff orpingtons. 3 barred rocks, 1 dominique and 1 austrolorp. Though im not positive which is the dominique. Thank you all who have posted all the generous knowledge on here and looking forward to getting to know more.
