My NN rooster has started sneezing again but not as bad as before. Last time the Tylan injections cleared him up quick but now he's really hard to catch. I have some water soluble 20% doxycycline from when I had to treat a parrot. I looked it up and found it can be used in chickens but said not to use in layer hens. Mo has 2 hens with him and it is not possible to move him since I have nowhere to keep him seperated. Plus, he stresses very badly when removed from his ladies. After the Tylan we didn't eat the eggs for quite some time but wondering if it's the same for the Doxy or does it mess them up forever? Anyone know???
