I don't disagree. However I believe the point being made regarding husbandry is that if an animal isn't eating checking and double checking husbandry is a good idea for a first step with troubleshooting.
In other words, improper husbandry may be the cause. If husbandry is on point then on to troubleshooting step 2.
Your case proves that even WITH proper husbandry, they can still go on extended strikes.
Congrats on the babies!!!! What was the pairing?
