I changed from organic grower/starter crumbles (min 18% protein) to organic layer pellets (min 15.8% protein) at 18 weeks of age (about 6 weeks ago). The chickens started laying at 19-20 weeks of age. Within the past month or so my chickens seem to have "lost condition" - they just look lighter in weight, not as fleshy in the breast etc. I don't know if this is related to the change in food, or the start of laying. They also do get garden scraps, and free range on poor range.(this has not changed). I'm just wondering if I should be concerned. I'm wondering if the protein level in the new food is too low? Any comments?
