About maybe 2 weeks ago we bought 3 8 week old chicks because we found out we had 3 cockerels, not 2 as imagined. They have been staying in a seperate cage in their run. We let them out from time to time to be with the now 16 week olds. We also have 14 week old leghorn chicks but they aren't doing so well with it. Everytime we let them out they will corner them and peck their heads. One of the roosters will chase and peck them (one rooster needs to go anyways). What is a better way to introduce them? Do we just need to let them go?
