I have some three week old d"uccles, three week old Ameracuanas and a 2.5 week old Silkie. My Silkie is still so small. It has some wing feathers finally, but it's so tiny. The three week old d'Uccles tower over it. It's trampled, often stepped on to get to the food better, squished in the corner at sleep time,etc. I did not expect it to be so small compared to the others. It looks like my Ameracuans did when they were 4 days old. I know with it being a bantam it will be small but.... so tonight I observed everyone running, playing,etc and little Silkie just sat there, with it's head slightly cocked watching me the entire time. It does not flee when I pick it up or anything. Several times the bigger ones ran right over it. So I removed him/her. It was just too sad. I don't know if this is failure to thrive (it seems happy otherwise, makes a mess in it's food dish) but it sleeps a LOT. But it does not peep much (hardly ever) does not walk around a lot investigating things like the other chicks. It pretty much just drinks and sleeps. It's not afraid of hands at all, even when it was first hatched. So I don't know if it's sick or who knows! It's tush is always clean, so no issues there. When I first got it, it slept so much I thought it was sick and then it finally began to eat and drink. I brought it in and let my 9 year old keep it in a small brooder in her room. She's always begged to let them come in her room (but of course, there are usually too many in the brooder to stay quiet) I have barely ever heard this silkie make a sound so whether it suddenly grows and thrives, or dies in there...we'll see I guess. It's hard when there are no obvious signs of distress, but you just KNOW something is a little off.
