Hi there, I have a 9 month old Serama Rooster, Levi. Appears to have large blisters between his toes... Stiff toes, Can walk but unstable... Eating and drinking fine. Has been on Oxytetracyline for a respotory problem. He was fine last night, I checked them about 9 P.M. He is in a Portable A-Frame coop, indoor portion and a 5 1/2 foot run off the back... They have a heat lamp on 15 hours 4PM-6AM. Getting a protien breeder mix by purina... It hit -6 last night, not sure what to do with him... I have 2 other hens that have small blisters between thier toes but the are not stiff... I live in eastren Washington... Thanks!
