I started out with 4 pullets, lost 3 to a raccoon; a friend gave me 2 Belgian d Anvers bantams because my lone surviving White Rock looked lonely. Was gone when the birds were introduced to the Plymouth White Rock about a month ago just after the raccoon incident, (I think the WR was still in shock over losing her buddies), so might have welcomed the company. Didnt see how she behaved, they just through the two bantams in the coop, they all three seem to be doing fine. Even though the bantams are only ¼ the size of the White Rock. Since then I purchased 2 Barred Rocks and 2 Golden Sex Link month old chicks. I divided the coop with some chicken wire. The chicks are about 1/3 the size of the Bantams, I have taken one chick out of the coop and tried to introduce her to the existing flock a couple of days ago, but the bantams immediately attacked the little chick. (no harm done was able to fend off the bantams quickly) I am thinking of waiting till the chicks reach the at least ½ the size of the Bantams before trying to introduce the chicks again, or should I wait until the chicks are half the size of my White Rock? Thanks for any help.
