I have a 1 yo hen who is having some pretty bad wet butt (feathers all around butt are wet with white residue). Every time I pick her up she squirts out a clear watery fluid. I have been watching her poop and it's also very watery, sometimes "spongy" and seafoam greenish. We lost a hen last year to these same type of symptoms. I want to say it's worms, but what do you guys think this is. I called the feed store and they recommended Wazine. I gave it to my girls yesterday and just gave them fresh water. I don't know what else to do. They are in a very large run, but also get time to free range and eat bugs. I have also noticed in the coop the poop is so watery, I have to change all the pine shavings every day because they are soaking wet. What can I do to fix this. I have read about dawn in the water, ACV in the water, and fermented food. I want to try thing things, but want to see if someone has had these same issues, and know what is going on. Please help me, I don't want to lose another one of my girls. Also if I use the ACV in the water, how much per gallon? Thanks!
* Side notes:
She is still eating and drinking, behaving normally. No major weightloss as of yet, red comb.
These girls are living in mild weather here in California. More like beautiful weather
They have a very clean run, and grazing conditions.
Their coop is well maintained and clean.
They are on layer crumbles with DE added, with flax meal and some sort of hollistic wormer. (Although I don't think it's working)
