Hello. I've been with BYC for a while but never really needed to post anything until now.
I have a 9 year old Sussex hen that has been without issue for most of the nine years I've had her. For the past week, she has been sneezing occasionally and has developed a sort of rattle to her breathing...
May be related...our new dog (not chicken trained yet) squeezed out past my husband and ended up chasing and biting one of our 13 chickens. We were horrified and worried about her (her name is Tippy). I noticed right away that she was breathing rough but I figured she had just run really fast...
