The Penicillin bottle says it's supposed to be room temperature. I've had it in the fridge so it's cold. Is it imperative that the medicine be room temperature or can it be cold or cool? Going to have to give it soon. Trying to heat it up a bit beside the heat lamp I have on my baby chicks. Need to know something soon if anyone can tell me. I was talking to someone, but they left before giving me an answer. Thanks anyone that can tell me.
