I would really appreciate some input on this.... I have 12 standard egg laying hens (RIR, barred rocks, leghorns), all the same age 8 weeks old that were hatched together and purchased together. They have had really no human interatction with them, except for me when I got them four weeks ago. Not very affectionate (them, not me). I was thinking of adding some polish hens I saw advertised. Maybe one or two. No rooster yet. What is the best way to do this? Would they be picked on too much? These polish hens are around 12 weeks old. Thanks in advance
