mulbery farms had a window of about 3 months that they had them in stock, unforunately mine all got sick or contaminated by foreign insects so I had to throw them away....luckily I have a bunch of eggs that im going to attempt to raise on my mulberry tree I have growing in my apartment. April, May, and June were the best months for availability to keep in mind for next year, otherwise try your hand at the eggs. If you buy them in bulk you can refrigerate them and just hatch as many as your chameleon will eat, like im going to try to hatch about 20 eggs at first, not all of them
