I'm writing about a 2 year old Americana hen. She had been fine, active & eating well. Yesterday acted ok, but broody. Today she is listless, eyes closed. She did walk out of hen house to eat, but then just sat on the ground & slept. Her vent looks swollen & there is a lot of creamy white drainage around the vent & surrounding feathers. I did a gentle digital exam & did not feel anything. Doing warm baths, heat, gentle massage, lubricated vent,... everything I read in articles on this site. No stores around her carry liquid calcium, so I y Have been trying small pieces of calcium tabs for humans, as the article suggested. My birds eat a good diet, oyster shell is available to them, & I sprinkle ground egg shells in their food. How would I know if the egg broke inside her? Is there anything else I should do?
