When you hear questions like how long can I leave the litter on the poultry floor before changing them? Well this depends on how careful you are in handling feeds and water in the housing so that they don’t spill and make the litters wet. The type of feeders and drinkers being used can also determine this.
However, once in two months is not bad and aside from that always change the litter whenever it gets wet or dusty even if it happens the next day after changing it the previous day, you must change them because they can affect you birds. The weather condition should also be considered as the litter gets wet faster during the rainy season. It is also good to change the litter when it is dusty.
