Not at all. A few days is not bad but dont wait too long at this point as you want to transfer before its done fermenting to give your wine a safe blanket of CO2 from fermentation. This is still an odd ubject as another wine kit manufacturer gas you complete the fermentation in the primary bucket then transfer so I dont think there really is a big deal with getting it in at this stage as I have done the other brands kits and they come out awesome that way to, but try to follow the manufacturers instructions so as not to void the warranty.
