This has been asked before, but a long time ago and got no replies, so am hoping there is someone knowledgeable around to help.
I got a white campbell drake with a white cambbell duck and a muscovy duck in February this year, all last years hatchlings I believe. The campbell started laying in March, one a day on most days, regular as clockwork. The muscovy laid occasionally. They continued up until the end of July when they stopped completely, and haven't resumed. They've not moulted and there was no change in their feeding regime or their routine. They are penned up with my chickens at night and have a lovely duck house (where they used to lay) and are free ranging during the day in a half-acre paddock - they actually have the run of 4 acres but generally stay in the paddock where their pen is. I have searched, but there is no sign of any eggs being laid in secret nests anywhere. They are fed adlib layers pellets (as advised by the breeder) and a bit of corn at bedtime, plus they are grazing and scavenging all day.
Is it normal for them only to lay for 4-5 months of the year? From what I've read, they should be capable of a lot more, so am I doing anything wrong? I've written this year off now as we are into the shorter days, but would like to improve their production next year.
