We have a RSL that will be a year old early February. She has always been smaller than our other hens, but she feels very thin when I pick her up lately, her breast bone is pretty prominent. My question is, could this be over laying? She eats normally, was wormed just over a month ago, acts healthy and happy. I know RSL's are bred for laying, but she is an egg laying machine! She started laying at 18 weeks, and has only taken two days off since then. She lays our largest egg out of all of our hens, has never had an issue with her shell, is laying through the winter, and even layed through her molt. I know it is her pullet year, so is this normal for her? I've tried upping her protein, scramble eggs, mealworns, tuna, etc. Maybe she is just a skinny girl? Is there anything else I can do to help her out? Any advice is appreciated! Maybe I'm just paranoid, but she seems so thin! This is her most recent photo.
