My first broody hatched her chicks 2 weeks ago. She has 9 chicks and has been an amazing mother. I have another broody sitting on eggs (today is day 13 I think) and tonight I went to check on everybody before closing up the coop and found this scene: All the chicks were standing around looking confused. A few of them were in the Broody's nestbox (which is weird) and I saw her chase them out. Then I realize that the "broody" is actually Mama-- and the real broody was standing all fluffed up nearby sounding irritated. So my stinkin' mother hen ditched her babies, hijacked my broody's nest and eggs, and chased her own chicks away! Once I realized what was going on I took Mama out of the nest box, returned it to its rightful owner, and put Mama back with her chicks. For a second she seemed irritated and tried to get back to the nest, then she settled down with her babies and went back to HER nest. Has this happened to anybody else? I'm pretty sure now that Mama is going to be stealing Broody's chicks when they're hatched. I locked Broody in the dog kennel (I had previously left the door open so she could take her daily walk) but what do I do now? I can keep Broody locked up for a little while after the chicks hatch, but not very long. It's really hot here and they need to be able to move around my yard to get cool in the grass during the day. I really wouldn't care if Mama stole Broody's chicks... but I don't want any bloodshed over it, and the chicks will be 3 weeks younger than her first set. Geez. Some mamas just aren't happy with the 9 kids they already have! Advice?
