Last week I noticed by Cochin didnt come running when I brought out their warm oats and yogurt. They all see me coming and jump and get all excited, not Roberta. So I snatched her up to check on her. She sounded like she had a stuffy nose. I consulted my group of long time chicken keepers and they suggested I treat the whole flock before they all get sick. I guess there have been many who have lost hens this winter. Anyway, we can't use the eggs now. Bummer. I decided to blow as many as i can and have a big basket full of eggs on my counter. At least i can enjoy them by looking at them...such a waste. Good news is Roberta is eating and acting 'normal' now. None of the others showed any signs of illness.
