Do you think I will have an issue introducing and older group of chicks to a younger group of chicks? I currently have 6 bantam silkies that are about 4 weeks old now, and I will be getting 15 day old chicks (bantam cochins, japanese, and seabrights) that are coming May 17th from Hoffman Hatchery. I will probably move that Silkies outside before the new group comes, but once the little girls/guys are about 3-4 wks I would like to move them outside, to the same pen. Do you think there will be any issues with bringing the two groups together? They will be in a large (8x13ft) chain link dog pen, with a smaller coop inside to get away from the elements. Any suggestions/thoughts are welcome!
