new guinea pigs - skin problem

Question
Hello, I am from Greece and
I am new owner of two young guinea pigs (not more than 2-3 months old), possible male and female. I had them only for a couple days and then i noticed under the eye of the male a laceration like a scratch. By the night time, it grow much bigger around 1 cm in diameter with hair loss and deep red color on the skin.Its covered with liquid looked a lot like blood all though I cannot see a clear wound. The poor fellow eats and drinks but seems less active now and I am afraid because its too close to its eye. I have no experience but from the info I see here I think it could be a fungal infection. Is it dangerous and what can i do?  
Also the female has two bold spots behind each ear but the skin looks healthy, just no hairs. Is that normal?
Thank you very much for your time reading this.  

Answer
Hi Dino

The bald spots behind the ears are normal provided this is only a small area. The male however does need some attention. The best thing to do is to visit a vet that has experience with exotic pets such a guinea pigs so that the wound can be treated and the underlying problem addressed.
