Gecko 1 Male, Gecko 2 Female, Gecko 2 Male, Gecko 4 Female.
Oddly Gecko 1 is a hard call. At 5 months of age it should be clear but this could nearly go either way. Is the area flat or a slight bulge? I have seen females very similar to this and more rarely males (young). Now i'm just being confusing.. "I used to be indecisive, but now I'm not so sure".
Nope... I'm calling it a male. 85% sure.
James: it looks to be a slight bluge but I thought would be more pronouced. Gecko 1 & 2 are a clutch pair and 1 has always been bigger than 2 but 2 isnt eating as much as 1 either so this could be why.
