Signed up to get advice...have 35 production reds..5 mixed breeds. One of mu reds went broody...she's 5 months old..wont eat or drink...put feed and water in her nest...she imbibed..but days later..when I took her out of nest to communiry feed and water....she "threw up" all contents. Didn't actually see her...but undigested scratch and feed on ground near her...a lot! Not sure what to do so separated her in own pen with food and water...she doesnt eat or drink...gave her rock egg to sit on...she lets me scratch under he chin...doesnt peck but makes protective noise. When out in open with others she flys up to me and roosts on my shoulder. Other chickens peck her...so...isolated her from them.
