I have a little chicken that I bought at a sale. I have her in a cage by herself. She, from everything I have read, has a cold. I have been told to use Vet RX on a Q-tip in the roof of her mouth or simply use vinegar. I read to use 1 tsp to 1 L of water. This should be her only drinking water. Does everyone agree with one of these solutions? Any other suggestions?
