Hi All: My son hatched 7 eggs over labor day weekend, our first experience with chickens. We ended up building a coop 8x8 large and a huge 16x8 outdoor run on grass. We are not quite sure who is pullet and who is cockerel since they are only 2 months old, but they are rather large and seem to be a mix of a several birds the farmer had on his farm...... At any rate we purchased 8 pullets from the National Show in Columbus yesterday for my son to show for 4-H he joined....they are a bit older but I found out they are Bantams of Silver Laved Wyandottes, Silver Pencil Laced Plymouth Rocks and Columbian Plymouth Rocks.....they are this years hatch not quite sure their exact age. Last night I separated them inside the coop inside a doggie ex-pen with separate food and water, when my son went in this morning several had perched on the pen and some had gotten up on the roost area.....seemed to be no problems, it seemed so my son took down the ex-pen and let them all out in the big run together to mingle and he monitored the group to make sure no one got into it.....well about a couple hours into the socialization the bigger ones started chasing and pecking the littler er ones.........I am concerned because I know a bit of pecking needs to happen to establish social order but I am concerned about how much to too much. I have again separated them where they can see each other but not interact or peck? Is that a bad thing? Did I rush too much?
