My 6 month old cochin bantam hen was fine last night. This morning, she is listless, won't eat, sneezing, and sticky liquid comes out of nostrils and mouth when she sneezes. Her mouth is kept open. Her crop seems mushy, the vet is closed on Sunday. What can I do? What is wrong? She is my most favorite hen! She's in the house now in a dog kennel right next to me
