I have an OEGB hen, 12 mo old, barely 13 oz, who is not "sick", but just seems to be surviving, rather than thriving. Poops are normal, no diarrhea, no sign of worms, though I haven't dewormed her in at least 6 months. No sign of mites or lice, vent and initial inspection shows clean and clear. Eggs have been laid regularly, however, it seems to be a bit more of a struggle for her than my other OEGB hen. Her more recent eggs have been exceptionally large, compared to her sisters eggs. I pulled her out of the flock, and into the house earlier this week, as she just looked kind of stressed. I am giving her some antibiotics and vitamins just as a precaution, but I would welcome some other ideas on pumping her up. She's gained at least .4 oz since the last time I weighed her 1-2 weeks ago. Eating and drinking are good, no ruffled feathers or sick behavior. I've been giving her yogurt, oatmeal, wheat bread soaked in milk, bananas, and other ripe fruits along with her regular food. Again, she doesn't look or act "sick". But her breast bone is prominent, and I know a few months ago, she was almost 15 oz, so she's definitely lost weight since then. I really want to get her back to where she was, and get some more meat on her bones, without over doing it. Any suggestions?
