If possible, allow the smaller chickens to be in the same area as your larger chickens, without them being able to touch, e.g., plac their two runs together. Leave it for a few weeks until they are roughly the same size, and then allow them to share a run. Do not be alarmed by fighting, the chickens will just be establishing a new "pecking order". If fighting continue alarmingly for over a week or until some chickens show signs of distress however, e.g. losing feathers, you may needto get rid of that certain chicken being bullied. (This is quite rare).
You can put them together right when the chicks are old enough to go in the coop. They will meet the other chickens when they are ready.
They have to retire old pets so they can introduce new ones.

I would wait until the younger chickens are at least a few months old. The older chickens will peck the younger ones, but they will stop at some point.
Show them a picture.
Yes, Wyandotte's are a great breed for egg laying and make great pets do to there kind nature. But just like any other chicken make sure all of your chickens are the same age or close to the same age, so they wont peck at each other. Be careful when adding new chickens to your old chickens, as the old chickens might not accept the new ones. If the don't accept them put them in a separate cage next to your older chickens to give them time to adjust to each other.
Old ones are old, and new ones are 13.
you can get old ones in a new game but not new ones in a old game
Old ones are old, and new ones are 13.
A lot of people say that the old ones are better, but I personally like the new ones.

new ones because they have more abilities and qualities and features than old ones:)
