Hello. I am a first time new to raising chicks. I have 5 breeds. Goldens, Welsummers, Iowa Blues, Delawars, & Americaunas. They are now 3 weeks old, being raised in a climate controlled room, (maybe getting babied a bit), and all seem healthy and happy. Question: I have one Americauna that is smaller than the rest, sleeps a lot, & far more than all of the others, and acts very timid with the other chicks. She is not getting picked on & they will cuddle next to her sometimes. I am thinking she is sick, but she doesn't seem to be in pain at all. Any advice please.
