i bought some Red Star pullets couple months ago, in order to get a regular supply of eggs. When they were young they were sweet. Now they're laying hens and have gotten pretty mean and out of control. They have plenty of food and water all the time. They also get extra treats. But whenever i go into the pen with a bowl or plate of treats, they start jumping up and snapping at my hands. Before i have a chance to put the bowl down, they've slammed into it and everything goes flying. It ends up all over the ground, on each other's backs. It's a madhouse. Even trying to get into or out of the pen or coop area (wherever they are currently shut into), the door opens and there are legs and wings and beaks pushing. i'm trying to get inside and half of them are crouching in front of me, the other half are trying to shove their way out. They even snap at my hands when i'm in the pen or coop and have nothing to give them. i don't know what to do to change this. Is it simply a matter of spending more time with them? How do i get them to calm down? Are Red Stars naturally like this? And then, now trying to integrate my two older EEs and not going well (another whole issue). Penny is holding her own, but one of the RS got the better of poor Grace once, and now they all gang up on her every time i try to put them together. It breaks my heart seeing Grace cowering in a corner, so i give up and let them back into their old pen. But that has to change as this new coop and pen was built for all of them, and i need that other coop for Silkie expansion. Any advice would be appreciated.
