Thanks again so much, everyone!
Still no change in my girl so I'm not sure if I should do anything - am tempted to let her ride it out a bit and see what happens? She's been sneezing and leaking for over 10 days now with no improvement or decline...
Nasal discharge is clear and does NOT smell like anything.
No coughing, weight loss or any indication she is otherwise sick.
I haven't yet found a vet who will treat chickens but if it comes to the point of me needing to get some meds for her, I'll get it done.
I only observed the stretched neck and opening mouth (gaping) when she was laying, she did it about 3 times in one minute and that was all (not before and not since). None of the other birds are doing it, so I'm thinking it was just a stretch??
Haven't caught any rats yet, the traps go off but they seem to escape.
Should I start a new thread on the safety of using poisoned bait to kill the vermin? I'm so afraid to use any poison around the flock, what if a mouse ingests it and then gets in the coop and the birds kill and eat the mouse?
I don't want to go off topic, sorry....
