Don't keep them in the same rack as bps. 85 is too cool for bps and much higher is too warm for corns. What are your room temps? You could probably just keep them at RT if the only option is the bp rack.
I agree, its probably too early for them to breed. Corns aren't like bps. They'll (usually) mate right away and be done in 30 minutes. None of this 24 hr lock stuff.
I'd separate them and wait and try pairing again in late March/early April. Put them in a separate tup lined with newspaper. If they're ready to mate, they'll go at it right away, and then with the newspaper you can check for "evidence". If they do mate, wait three days, pair them again, wait three more and pair them for a total of three times over a week. That will do the trick.
As for the offspring. They will all be 100% het hypo, amel, and anery. If there are any hets, then you'll be able to tell. If you get a smaller clutch, then you might want to do two years to fully rule them as not being het for a particular gene. I've had 20 clutch eggs and only get 1 homozygous animal, when the ratio should have given me 5.
Good luck! And feel free to ask here or PM me with any questions.
