most of these medicines are prescription only, best bet would be get your young birds tested by Retford Poultry and then they can prescibe what is needed... in meantime starve the young birds for 24 hours to empty all crops, build up with light grains there after, virkon-s or vanodine v18 in the water will prevent the virus spreading, belgica 4-in-1 to get the droppings back firm again, will take you a minimum of 2 weeks to get these youngsters looking anything near normal again, next time dont wait two weeks before asking.... keep them in for at least a week and definetly no training!
