I have one chicken (Miss Ray Ray) that is bow legged. She is short and really fat and acts like she wants to lay. She is semi active, gets up to eat and drink and loves treat time. Her comb looks flat with no real definition, looks like it got smashed. She' is a sweetheart but seems to want to be off on her own. We moved the nesting box up today and she seems content to stay there where she doesn't get walked over by the others. She's about 12 weeks old. Is this something to be concerned about? Here are some pics.
