It is advisable to ensure that feeds do not finish completely in the feeding troughs at all times, therefore give them enough feeds at least two times in a day. Example: early in the morning and later in the afternoon. Also make sure that the quantity of feed served to them is such that will give all of them access to the feed.
Sometimes most poultry farmers always want to know if it is good to serve birds feed at night. Well as in the case of layers, the quality and quantity of eggs produced by layers are usually determined by the quality and quantity of feeds given them. Most times, it is advisable that light is made available for them to be able to eat into the night. Some farmers leave the birds to eat until around 11.00pm which has greatly helped in increasing the number of eggs produced.
