Hello! Last night I went out and checked on my calls. They were all ok but seemed stressed (hence the reason I went out and checked on them after already being in bed). All were fine and sounding normal. My one female call has been a little sneezy but nothing to crazy. This morning I went out to check on them give them fresh food and water and she no longer has a "quack" it's a very high pitch squeal. Almost sounds as if she strained her trachea from quacking too much. She's the smallest of my bunch but one of the loudest. I hope she will be ok. I put acv in their water this morning. And I have de wormer at home as well. Please HELP! I don't want her to be sick and pass away!
