Hello all! thanks in advance for any help! I have a mixed breed/age flock of 20 chickens, they haven't laid in about 4 weeks. They have been wormed (pumpkin seeds) the older ones seem to STILL be going through a molt, I have treated each bird with Adams just to make sure it wasn't mites or lice. After checking each bird I couldn't find any signs but treated anyway. I have about 4 hens that are about 3 years old and they all look terrible, my barred rock is missing so many feathers! This morning I heard a couple of sneezes, I picked up my lakenvelder hen after she sneezed and she had mucus and a bad smell. My best guess from Storey's Guide is bronchitis. After a very long drought we have finally gotten rain...a LOT of rain, it has rained nearly everyday since winter started! The runs have become mud pits and as much as we have tried have had a very hard time as it never stays dry long enough. I had to clean my coop off schedule as well b/c it was caked with mud. I do not know if this is why the caught bronchitis or not with the cold and wet/ muddy conditions they have been in....I try to let them free range as much as possible but they won't come out in the rain. What is the best/cost effective way to get them all treated quick and stop it from spreading. Effect on the eggs is not a concern since they are not laying anyway! thanks!
