my black sex links are now almost two weeks old now my red sex links are almost five weeks now So I have 11 red sex links that are almost five weeks old. My first time having chickens I could not believe how fast they are growing. I have 6 black link chicks that are just almost 2 weeks old. I have been keeping them separate because there was such a size difference. But from all I have been reading about here and hearing about I should be getting the chicks together as soon as possible. I am going to try letting them all have a visit together tonight and then back to separate areas. Does anyone have any ideas on how to make this as easy as possible. I have been putting a couple red sex link in the black area once in a while. For the most part they seem to want to ignore the little chicks. But the black chicks are right up front not wanting the red sex link in their area. They pick at her tail feathers, or flap up in her face. With the size difference I find it odd the older chicks just seem to ignore them. I have to say I am loving all of them already. They have such personalities. I have several that just light right up when I come into the room where they are for now. They come to my hand wanting a lift up to the top of their box. Most of them can now fly up. There is even one when I pick her up she cuddles down into my hand and goes to sleep. I can see whey people say it is addictive to have them. Thanks everyone for all the advice.
