I know this is a dumb question, cause it could be a million things. One of our Silkies acted a bit odd two days ago, but was broody, so we didn't pay too much attention. She died last night on the nest. Now one of our Silver Spangled Hamburg hens is acting sick, standing around, not eating. We have been intending to deworm them this month anyway; just haven't gotten around to it yet. We will tomorrow. We dewormed them this past spring with Fenbendazole Safeguard, which is supposed to kill all types of worms except tapeworms, and that is what we will use tomorrow. Could worms cause this? They don't really seem to be losing weight; hard to tell as they run all day anyway and don't carry a lot of weight. We are going to start them on Aviacharge, too. Any other ideas, suggestions, comments?
