I live in coastal south Texas and I've decided on Buff Orpingtons for my backyard bunch. My son built a 3'x3'x6' chicken tractor for me for Mothers Day so I'll be ordering my chicks tomorrow! I've raised guinnies before and chickens when I was a little girl (a long time ago). I have two grown children, one granddaughter, one rough coat collie, one 16 yr old, 22 lb. cat and two ponds of tame (yes, tame) goldfish. This may not be the place to ask this, but my 'spousal equivalent' (for the past 17 years) has 10 black sex links on our property on the bay. I'm ordering more chicks than I need for the back yard so my question is; when are the extra Orps old enough to put with the adult sex links? I understand that you are supposed to do it at night and in the morning the adults assume that the others have always been there. Let me know what y'all think. This looks like a great forum. Thanks!
