I feel safe to say that when a female Culumma brevicorne shows a golden color in her occipital lobes that she is receptive. Morticia showed no signs of rejection (twice) as Gandalf approached.
I use Repti Calcium without D3 every feeding and Repashy Calcium plus LoD twice a month for all my chameleons except jacksons they get the RepashyLoD once a month.
As some of you know I have been keeping Calumma brevicorne for a couple years and decided to start a small breeding project awhile back. Last Friday my hard work paid off some. Here's my first CB and hatched brevicorne 😊😊😊 only one so far.
