Review on Brinsea Products Mini II Egg Incubators Hatching Mats: Optimize Hatch Success with this One-Size Solution by Brenda Quiroz

The disc has its pros and cons. It is pre-cut for Brinsea incubators so it fits perfectly and is very easy to swap out on day 18 when the eggs no longer need to be rolled. You can make changes in no time and the incubator will recover fairly quickly. On the other hand, during the hatching process, the mats get wet and the chicks can slip and slide in the grooves as they are quite deep. The incubator is small, once a few eggs hatch, it's also full. Others recommend using a rubberized shelf liner and I plan to use that next time to give the chickens a firmer footing.
