I have some Silkie chicks that are almost 5 weeks old. Occasionally have taken a hen to look into the brooder box to get them used to seeing each other. Today I took one Silkie outside to meet the others. A couple of hens jumped into my lap to check it out. Things seem OK so I put the Silkie on the ground, almost instantly one, of the hens pecked the Silkie head and another fluffed up and was about to peck before I stopped her. Now the Silkie chick is showing signs of brain damage. The problem is in a week I need to introduce the 10 Silkies to the 8 standard breeds and I only have one coop. Are the standards going to kill all my Silkies?! I read here that they should do fine together, after this, I don't know what to do. Please help with any advice that will make a safe transaction. I really don't want to lose any more of my sweet Silkies.
