We have three baby chicks that are two days old and we have another broody hen sitting on eight eggs. We didn't see what day she started sitting on the eggs and then forgot to write down our estimate of when it happened. (we have our own six-month-old infant son, so sometimes things we plan to do escape us when it's time to actually write it down on the calendar!) But that said, she's been sitting on the eggs at least a week and a half already, so we're probably looking at having chicks that are about 1-1/2 weeks to 2 weeks younger than the three that already hatched. We have raised chicks before that were one week apart in age without any problems from them pecking each other in the brooder. But is is possible to raise them that are up to two weeks apart in age? And will the mama hens try to kill each other's chicks? We only have one brooder so we're hoping we can raise all the chicks together. But if not, just let me know your opinions and we'll arrange another setup for the second batch of babies. Thanks!
