Hi, I have seen some discrepencies as of late and wish to put it to rest. Hard to find a straight answer. Would someone please share the correct dosage information for Tylan 50 please? I wouldn't mind it for both standards and bantams, and adjusting for different age ranges/sizes. Frequency also? Contraindications or issues of concern, to my understanding, are stones. I just want to get all of the information. Thank you to those who don't mind responding, I appreciate your helpfulness.
