i have a 2 year old austrolorp (spelling ) hen that is sitting in the nest with clear (egg white?) comeing out of her vent.. i palpated her abdomen and didnt feel anything hard, like a stuck egg. While palpating, some black stuff came out of her vent.. along withh more white stuff she is breathing hard, and seem warm, but its really cool out side, she also seems almost stiff... she has been sitting in the nest all day, has not gotten out. i offered her food and water, she didnt want any of it. there are no vets in the area that will attend to a chicken help! should i cull her>?
