Mixing week old Barred Rocks with 4 week Silkies.

[bigspringshatchery]

How can I mix these two? I tried with one br last night and the silkies started pecking the brs toes. There are only 3 silkies and I have 16 brs. I just need the brooder the brs are in bc I had 2 guineas hatch yesterday.

Split the brooder in half and house the guineas with the BRs? They are probably closer in size than the silkies and BRs.
