I hatched out 6 sillkie babies 10 days ago and all were doing great until yesterday when my favorite of the bunch started sleeping a lot, isolating itself, and looking generally lethargic. I have given it water with a bit of sugar, and chick saver, and it has eaten a tiny bit. They are getting medicated chick feed, today I blended carrots, feed and a bit of oil and HB egg (recipe from Silkie breeder), and it ate a tiny bit. It will wake from time to time and walk a little bit, but not at all as spunky as everyone else. This chick is quite a bit smaller than the others as well. Any ideas? Thank you in advance!
