Previous birds have stopped laying over winter and coming back into lay first half of Feb, they were Sussex, Maran and Columbine, now I only have White Stars , RIR and Black Tail and they've all layed non stop over the winter, oldest bird is two so it might be down to age but my previous birds didn't when they were young.
So I haven't a clue !, I haven't changed anything, I wish they would stop over winter to give themselves a break.
As an aside, what a lovely breed RIR's are, first time I've had them, I thought they'd be a bit dull for some reason but they are by far the funniest most friendly bunch I've had.
