just thought i'd add that just like "true" chameleons, brevs can also lay infertil clutches, and they can also become egg bound, so just make sure your supplimentating is suitable to the husbandry and lighting, and gutloading of your pygmy. some keepers use 5.0's, some just use daylight. whatever you use though will affect your supplimentation.
i'd also like to add that brevs can lay 1-6 eggs with 3-4 being an average
