Egg Binding

Egg binding is when a hen cannot pass an egg, often due to large/soft-shelled eggs, low calcium, or obesity. Signs: hen sits puffed up, strains repeatedly, walks penguin-style, may have a visibly distended vent. Treatment: 30-minute warm Epsom salt bath, calcium supplement (Tums or calcium gluconate), lubricate vent with vegetable oil. If still bound after 24 hours, see a vet — can be fatal.
