I have 8 ex-"free Range" chickens (I say free range but actually after picking them up and going into the barn they eat, drink, roost and lay in i'm a bit sceptical of the conditions commercial "free range" chickens live in) anyway since getting them one had really dirty feathers around her vent I thought it would clean up not living in a barn with 2000 other hens, after a few weeks it didn't clean up so I washed her with a hose and broke up the dirt on the feathers but they just got dirty within a few days so I cut all the feathers away around her vent I have now noticed a white sometimes clear discharge running out of her vent which I assume was making her feathers wet then they'd pick up dirt as she rolled around in her dust bath. She also layed an egg with a soft shell with white sticky discharge on it other than that she seems very healthy.
Any help would be much appreciated.
Thanks in advance.
