We picked up 2 silkies yesterday, and we put them in with our week old RIRs. We also have 3 3 week old barred rocks. One of the silkies in particular seems to sleep all of the time, and both seem to sleep a lot more than the RIRs or BRs ever did. Is that just because they are silkies? I checked and ensured they do not have pasty butt, so I don't think they would be sick from that.
