I have a hen that is going around making a noise with her mouth open. I’m not sure if it’s gape Worms or Respiratory infection. I’ve had her two weeks and she’s been fine until yesterday. I gave her a vet RX and Wormer. I put apple cider vinegar water down her throat with a dropper. I’m not sure what else to do I let them free range from 6 to 630 at night is that too long for them to free range I need any advice anyone can give
