Im a little lost on this? Do you have to burmate them to get them to mate? Ive read it can be unsafe...i dont wanna risk my geckos lives over that... if so and its safe how low should the temps get? how long should i leave them be like this? i know the seasons done but i wanna know before hand. When should the burmation start? and what are good weights? All mine are 55+ grams easy.
