For the record, when I examined all my internal layers, none of them had distended-feeling abdomens, however, upon doing a layman's necropsy, we found many masses of infection and egg material in the oviducts, with layers like onions. Normally, with a standard size bird, we give 1/2 cc, twice daily if the infection is bad, or if it's a dire emergency and we want a 1-2 punch, we do a full cc, which may not be recommended, but if the bird is on its deathbed, seems like it may be called for, but that's me. Normally, you'd do no more than 3/4 cc.
