My Red is lethargic, not eating/drinking since yesterday. Today her belly is distended and I caught her standing in the nest box for over an hour (didnt see when she went in). I gave her a warm bath for 20min and she started panting (she's always the first to complain about warm weather). I felt around the inside of the vent and i *think* i felt a soft egg. I came across a few articles on calcium injection for egg impaction, but no dosage info. I have "poultry nutri-drench" that has 0.4-0.7% calcium and is taken orally. I also bought "calcium gluconate 23%" for cattle/sheep. Will one of these work?? How much calcium is needed to expel the egg?
