15 month-old hybrid layer acting normally this morning found to have a 3/4" wide by 2" long piece of thick mucousy tissue hanging out of vent. Cleaned up and isolated. Tissue appears to be attached to inside and with a small opening at 3 o'clock position that is leaking stool. Found a bloody egg on floor yest, but have another walking around upright and wont hop into nest box so thought the floor egg was hers (another story). Wormed the flock of 85 last week due to evidence of round worms. Hen is now isolated and drying from the clean-up inside. Tried to reduce the mess back up inside her, and gently pulling to assess points of attachment. No change with any of this. Suggestions? Cant figure out how to post a pic using this iPhone.
