Emerald Swifts

Hi
I have a male and female Emerald Swift, the female is shedding but the male as 2 black (burn like) marks under his front 2 legs. I cannot see that he has burnt on anything as lights are on outside. Is this part of the shedding with the male or do I have a problem of another kind. I have only had the swifts a few days and they have been fine until now. He is still feeding and active. Thanks

Can you post some pics of the black spots? What are your temps and humidity and heat source? What is the substrate in your enclosure? Are you housing them together?

Can you post a picture of the marks?
Male emerald swifts have two blue marks on its underside that run parallel to the body.
