I have 5 Little Giant incubators. All have the additional egg turners. The egg turners all plug in separately from the incubators. The egg turner instructions say not to plug them into an extension cord however my setup requires me to do so. Is there a workaround to get the egg turners to operate under those conditions. Send sort of amperage box or volt box to get them to operate. Any help from all you backyard chicken er's would be greatly appreciated
