Is it OK to give Twin Pen Longacting to a Nursing EWE? She is not doing well Since Triplets yesterday. Maybe Mastitus? Not eating hay Ok on grain. Lays on side alot and sometimes can not get up, just as she did when pregnant. Udder is huge at least 2 gallon size and Back of Udder is very firm, side have softened some since birth. The smallest I am Tube Feeding. Udders are very low to ground and this baby has not found it yet.
