These 3 hens are all in the "sick kennel" because they are showing the classic signs of cancer. The one in the middle started doing this gaping thing on and off today, and I'm wondering if I should treat her for a respiratory condition, or does this look like something else--- a polyp in throat, gapeworm maybe? The last hen who I had do this, I treated w/ Baytril. She died after a few weeks and a necropsy showed only cancer. I know this one is going to die, but I'd like to give her a nice few more months of life, if possible. Any thoughts? Thanks so much!
