My chickens have stopped laying, what should I do?

If your chickens are no longer laying eggs (and they previously did) there may be a number of reasons they have stopped.  You might need to ask yourself a number of questions to determine the reason why they are no longer laying. 
How old are your hens? Typically, hens will slow down laying once they are 2.5 years old and eventually stop laying altogether. 
What time of year is it?  Hens don’t tend to lay all year round and they will probably stop in the winter months

Are your hens going through a feather moult?  If they are moulting they tend to stop laying too as they require all of the nutrients in their diet to regrow feathers. 
Are your hens healthy? A health check should rule out any visible health issues.
When were your hens last wormed?  A high worm burden may prevent your hens from laying.
Do your hens have adequate nutrition?  You might want to consider supplementing your chickens with Nettex Poultry Egg and Shell Support Powder – this complementary mineral feed is specially formulated to improve egg quality, assist digestion and provide nutritional support for laying hens.
