I just got my three ladies last Saturday from a local hatchery. They are around 18 weeks. This is my first experience owning chickens and I feel like I need some advice. I want to know if my chickens look like they weigh a decent weight? They look healthy to me and are eating their food, and others extras very well. I went to pick them up last night to put them in their coop (they are getting used to living in a coop) and they just felt really thin...I could feel their breastbone. Is that normal? These are Golden Comets by the way. After looking at my pictures, can you tell if they look like a "healthy" weight?
