Like I mentioned with enteritis, intestinal worms, protozoa, bacteria can all cause this sort of problem with blood in stools. I am not sure how much Hygromycin-B is contained in the amount you fed your birds. The fact that you fed for 5 days should have done the job. I've tried Rooster Booster Multi-Wormer, which is the same as Strike III, but in a crumble form. I found myself mixing it in a wet mash in order to get them to eat it, and eventually worming again a few months later with Albendazole. There is noticeable difference I've seen in the health & activity of birds after deworming, even if the infestation wasn't bad. Diet can cause a variety of color in droppings too, but blood, excessive mucous, watery bright green or yellow, foamy are descriptions that indicate intestinal problems. If you haven't done a flock treatment for the hens with Amprolium for Coccidiosis, you may want to do that beginning Monday to Sunday. You've been giving poultry vitamins-electrolytes with the probiotic powder in waterers?This poop is from the 4 outside birds that were wormed with Strike III over 5 days and I hand fed them the pelletts so I know that each bird got its full dose. I am not seeing the peach color or blood in the poop for the last few days since they have been given the probiotic. Rooster was wormed with Strike III the same way but I did not get photos of his poop yet.
To ochochicas,
1.6 ml is a very high dose of Tylan 50. You are treating respiratory problems? If so, the dose I always used was .5cc once a day under the skin on the back of the neck. If the bird was 5 lbs or more, I'd give an additional .5cc in the breast muscle. It has been a number of years since I treated a respiratory problem, but I never remember having to do it for more than 5 days.
