I have one 4 day old BCM chick. She is the only one that hatched out of 14 shipped eggs. I thought she was so lonely. Then yesterday I had 2 Dorking chicks hatch out. They are so cute and tiny. I put the 4 day old in with the 1 day old chickens and 4 day old constantly pecks their toes and then she started pecking at their eyes. I was so afraid she would blind one of them I took her back out. Now I have to keep 2 areas clean. I put cardboard between the 2 groups in the brooder and she still tries to peck their tiny feet under the cardboard. I am glad she isn't dinosaur size! Anyone have suggestions how to mix them? HELP!
