One of our EE hens (4 y/o) has been "barking" since early December. First, we thought it was some kind of illness and tried her on antibiotics. No improvement. We waited a week, tried a different antibiotic, no improvement. It now seems she must have something stuck in her larynx/trachea. Is this possible? Apart from her "barking" she is totally normal. Her comb is red, her feathers are beautiful, she free ranges and interacts normally with the rest of the flock. When she "barks" she shakes her head and she gapes afterwards. This is most common while or immediately after she has been moving. All her other chicken noises are normal, clucking, cooing, etc. We have read so much and can't come to any other conclusion. Does anyone else have experience with this or other suggestions? Thanks in advance for any advice! --Pam
