I am a professional queen breeder and producer. I have 450 hives and 1400 mating nucs. I am considering replacing my actual wooden mating nuclei by hard polystyrene baby nucs. I know of two swiss models (Swi-bi and Apidea). Does anybody know anything about these models or other models? What are their drawbacks? Do the ants chew them up? Does anybody know a queen breeders who has used or is using them and could be a source of information for me? ***************************************************************** Jean-Pierre Chapleau phone: (819)828-3396 1282, rang 8, fax: (819)828-2248 Saint-Adrien de Ham, QUEBEC Canada, J0A 1C0 [log in to unmask] *****************************************************************
