Very, very new to this - actually first time I have posted ANYWHERE! I am a first time chicken owner. I have had my girls for 18 weeks and just purchased more as 2 of the 6 originals turned out to be boys! One of the new girls purchased 2 days ago (from a reputable breeder) a Rhode Island Red is rattling when she breathes. She was fine when she arrived at our house and I think she may have breathed in some water, not being used to the container ur water is kept in.. Today her rattle is worse, but I'm sure she is still eating and drinking and looks fine. The other two girls are great. Any suggestions please.
