How old is the bird that is pooping that?
I would go ahead and start the Corid for this particular pen - what 3 hens?
I wouldn't necessarily treat the other coop if you aren't seeing poop like that.
If you are sure who is having the bloody poop - I would also direct dose her with undiluted liquid Corid at a rate of .10ml per pound of weight once a day for 3 days.
This is in addition to her drinking mixed Corid water as the only source of drinking water throughout the day for 5-7 days.
Dose for Liquid Corid is 2 teaspoons per gallon of water or Powdered Corid is 1 1/2 teaspoon per gallon of water. Give for 5-7 days as the only source of drinking water.
Don't add anything else to the waterThe bird is 10 weeks old today. She is a barred rock. Thank you for the dosage information. I had only put in 1/2 tsp of powder per gallon of drinking water.
do you have a recommendation on how to individually direct dose her with the powder? (That is all my Store had available)
Thank you for your help!
