Hens may stop laying or may not lay for a number of reasons.
- The age of the hen – as they get older the amount of eggs may reduce.
- The health of the hen – illness or parasites can hinder laying.
- The time of year – the length of daylight can affect egg production.
- Changes in the type of food given – this may cause problems as the nutritional content of the food may vary.
- The introduction of new birds to the flock – this may cause undue stress for the hens as they re-establish a pecking order.
- Significant changes in routine – can cause stress for the birds.
- Housing conditions – unclean, overcrowded, dark and cold conditions can cause stress and or illness which may affect egg production.
- Handling and movement of the poultry – transporting hens, overhandling, incorrect handling and sudden handling may hinder laying if this causes stress for the birds.
- Vermin and predators – the presence of rats, mice, cats, dogs and foxes may frighten the poultry or cause undue stress.
