So as I'm sure you know and are tired of hearing me complain I can't get my roaches to breed, how can I tell? I bought 1k nymphs to feed off, so most are pretty small. I added heat recently, and noticed some -very- small nymphs. Would these be new babies? The 1k nymphs were about 1 1/2 months ago, so most are just over half an inch. Was just curious if I'll see left over ootheca or any telling signs besides tiny nymphs. Any advice/help is greatly appreciated!
