Seriously (shame about Arsenal, but at least West Ham won yesterday!!!), chickens go off lay for a number of reasons. They could be coming up to moulting - and before anyone says it's the wrong time of year, yes, it may well be, but 3 of mine have been moulting now for a couple of weeks and I've had no eggs at all from them. Annie, get them some Poultry tonic from wherever it is you get your feed for them (you can put it in with their water) or some poultry spice, which they love and can be mixed in with their food. This will help to keep them in good condition, whether they're moulting or not. Another thing that could be affecting them is the weather. If it's been cold & wet where you are, that could be the reason. They don't mind the cold, but they don't like it when it's damp. My girls are all pretty ancient now, apart from one, but even the old ones lay, even through the winter. Are yours getting plenty grit as well, because that can affect their laying. At a year old, they should still be laying well, at least every other day. Give them plenty greens and make sure their nest box is nice & cosy and clean for them. There's one other thing - they're not eating the eggs, are they? Let me know how you get on. Good luck, K xx
