Today is day 15 for the 1st batch and day 5 for the second batch. Everything is going great! I candled all 16 eggs from the second batch to make sure I didn't miss any unfertile eggs, and all of them are growing exceptionally well all 16 are still good. I had one question though as the first batch will hatch in 8-10 days from now the second will be 10 days behind them and the third even further behind. Will the older chicks pick on the younger chicks? ( I have never had split hatches like this so I have never had chicks of different age) If so I have no problem with getting another brooder.
