I had some that never would. All of the hives I started on 5.1 as per the regression instructions then. They all did that well. Most struggled with 4.9 producing a hodge-podge of small, drone and distorted. Several hives could never get it done. I put frames that were drawn as well as any in the hives that couldn't figure it out. Several of those queens couldn't lay in it. None (0) thrived. All had mites and were in full collapse when I threw in the towel.Queens are reluctant to lay in the small cells, my queens would go 3 to 4 weeks before they would start to lay.
Send them an email and ask them why they issue this warning. I would be very interested in hearing "their" response to your question, and please post their reply here if you don't mind.In Brushy Mountain's catalog it warns that only experienced beekeepers should use small cell foundation. Why is that?
An interesting choice of words. I suppose I could have said mine didn't go smoothly.....as some have claimed here. But I didn't because that sounds unnecessarily confrontational. Many have different experiences....which to my thinking is what the op asked. Just sayin'.as some have claimed here.
