Need advice regarding my 5 day old Silkie chicken?

I have always force fed my chicks 3 to 5 tiny stones [BB sized] to be certain they had grits for their gizzard. When I had a hen care for them and they were lose out doors I let them find their grits. Next I give them crumble and then pellets. I give some scratch feed and wild bird seed mix and they can choose what they need. The "pasting-up" of feces on the but is usually a sign of stress and will occur when they are shipped to me. Keep it moist with warm water and scrape it off with a butter knife or like tool. Give water and feed 24/7 so you don't need to get up early and see what they need. Stress is also form crowding, too cool or too warm, hungry and thirsty. At 5 days old they should be in 95 F brooder and reduce it 5 degrees each week till you are at 70 F.

I THINK if you got one of the hens to go broody, and then timed things right, you might just get her to think she hatched it herself. I've introduced guineas to my flock (chickens 8 weeks old very large breeds, guineas 4 weeks old), and I've just reintroduced a rooster that had been isolated for about a month due to illness (prolapsed rectum). In both cases, I put the 'introducee' in a pen-within-a-pen for about a week, to allow the other birds to see and sort of get used to the 'newcomer.' After remoiving the pen, in both cases, there was a little pecking, but after a few hours, things had settled down, and after about 24 hours, I did not see any conflict at all.
