Sudden drops in egg production can have several causes. First, check for environmental stressors - has there been unusual noise, predator activity, or temperature fluctuations? Second, examine your birds for signs of illness. Third, consider whether there have been changes in water quality or availability.

I recommend checking feed quality (ensure it hasn't gone moldy), ensuring constant access to clean water, and looking for signs of disease. If the problem persists for more than 3 days, consider having a vet examine a few birds.

Several factors can affect broiler weight gain. First, check that your feed has the correct protein content (should be 20-22% for this age). Second, ensure feeders are never empty and that birds have easy access. Third, check water availability - dehydration quickly affects growth.

I'd also recommend checking for parasites and ensuring proper ventilation in your poultry house. Sometimes adding a vitamin supplement to water for 3-5 days can help boost growth if other factors are optimal.
