I have 11 hens, 6 from an original hatching and 5 from two months later...all purchased birds. My older 6 have a pecking order that has put the smallest Smurffette as low man on the totem pole, she in turn bullied the younger five so bad they would not even leave the hen house and seldom even came down out of the roost poles.... time and growth spurts has evened the playing field finally and the fact the younger birds have matured into layers and have even more size to grow into because of the breeds. I had made all kinds of hiding spots and added several new perch bars inside house and the run itself to try to coax them out even went so far as to kick them out of hen-house twice....thank goodness it finally worked itself out....I really liked my Smurfette ( an Ameraucana mix) but was getting to the end of my rope.....
