Asking for my friend... My friend has three Rhode Island Reds. All are about 2 years old. She has recently (very unsuccessfully) been trying to introduce new chicks into her flock. The three girls have pecked at least two baby chicks to death they're bullies lol. Today, she noticed that one of her girls hasn't moved from the nesting box all day. She's thinking she might be broody. She has two buff Orpingtons that are about 2-3 weeks old and she wants to try to introduce them into the flock (and have them actually live this time). In our research we've found that we can possibly introduce new chicks if their is a broody hen by "passing" the chicks off as hers. The question is, are the buff's too old/too big for her to try and pass them off as the broody hen's babies? Any help would be appreciated.
