I acquired 4 domestic monkeys in September, ranging from 11-17 grams. They currently weigh in at just under 40 grams, 33, and two at 30.

Question:
What is "normal" adult weight for M & F?

What is age of maturity? Two of them have distinct nuptial pads and (at least two) are croaking each evening. So, I have at least two males; what are the odds the big one is a female? I will get some pics posted tomorrow in hopes someone can help with sexing.

In my zeal due to the behavior of the males I set them up in a rain chamber all this past week; lots of croaks but no amplexus; perhaps the females mature more slowly? They were "sort of" cycled; our ambient humidity has been very dry and I opened sliding door each evening to reduce temp around their tank to about 73-4 for past 2 months.

Since I am sure someone will ask, here is husbandry (for anyone who wants to read the details)
Screen enclosure 16 x 16 x 30 (will get larger one eventually)
Temp of house extremely consistent at 76-80; basking spots hit 95 degrees, no heat at night. Uv lamp 3 hours/day
Dusted crix but trying to transition them to dubias and they are starting to take them
Absolutely spotless, planted (with silk plants and vines) enclosure with treated water

Have never bred frogs but excellent success in the past with torts, chameleons, and parrots and very much want to have these guys produce when they can.

Any "monkey breeding buddy" would be welcomed!

Thanks
