I have a 10 week old japanese bantam roo that has a prolapsed vent. it is very red at night and almost normal color in the morning. wondering what to do for treatment. can I use preperation H? does it get better? when the redness is gone it still looks a little bit swollen. he is eating and acting normal. would hate to lose him if he can be saved. started feeding plain yogurt this morning. should he be isolated and if so for how long. is this a genetic weakness ?
