Hi all .. I'm rather worried about my female, thismorning she seemd to be shaking and her eyes are looking half closed .. signs of respitory infection I fear, but Ihave been putting anitbiotic drops in her drinking water for 2 weeks now.  When I say shaking I dont' mean great jerky movements .. just quivers almost.  Do you think I should try and giver antibitics by mouth also?  I don't want to lose her. Help please ~Heather
