Hello. I just got a new Americauna hen, about 5 months old. Not laying yet. I have one Golden Sex Link. The Americauna, "Claire", is separated from the sex link, in her own coop and run in a different part of the yard. She looks well, active, eats heartily, scratches all day and all in all a great chicken. I noticed today a watery mucus occasionally coming from her mouth. Not all the time, she eats then it might come up. Her beard is a bit matted down, most likely from the spit up. I got her from the same spot my sex link came from. She will stay quarantined for at least a month, so do I start antiobiotics? Her run has sand/dirt combo and was covered by pine nuggets she has scratched away. I rake the run in the am before I put her in. I also checked her crop and didn't feel anything and her nares and eyes look good. Is she getting 'used to' our yard or should I start a round of antibiotics to be sure? Thanks.
