If then else with fixed delay

Post by ebr567 »

Hello,

I have sheep that are move through stages of pregnancy using fixed delays. They enter the breeding pool on a specified breeding date, then after 30 days they are either pregnant if they conceive or are culled if they do not conceive.

If the conception rate is below 60%, I would like to not push them into either pregnancy or culling, but have them go back into the open pool for another chance. How would I do this? I don't believe I can nest an IF THEN ELSE statement within the FIXED DELAY. See attached.

Thank you.

Apologies for the missing units. Hopefully I didn't mess anything up as a result.
