Hi, I need advice regarding my 11 month old hen. She had Wry Neck and I treated her with polyvisol and vitamin E with selenium and took to vet. Lab revealed she has coccidosis and mega worms. I wormed her and gave her Corrid. She is much better with head 90% up, but it it very crooked and her balance is therefore off. Today is last day to worm but I will continue with Corrid in her water. I am not sure if she is getting enough Corrid because the dosage is for 1 gallon of water and she is one chicken so how do I formulate that down to say four cups of water? Anyone know? Can people share if their older chickens's crooked neck went away with time or not? Thank you! I am concerned about putting her back in the coop and I have no other place for her! Thank you!
