I have a little one who is small and peeps a lot. She is with a broody, so it is hard to keep track of what she is or is not eating and drinking. She is suddenly so much smaller than her siblings! I make sure she gets more than her share of egg yolk when I take some out to the rest of the brood. She had a bit of pasty butt (I thought the momma hens were supposed to keep that cleaned up?) yesterday, so hopefully she is feeling better today now that is cleaned up. I think, being smaller than the rest, she is getting chilled. She is trying to get under momma all the time, and when that fails, under one of the other chicks. I have two unrelated chicks that I failed to get the momma to adopt, so I am thinking about adding her in with those so she can get under the brooder light where it is warmer. I did see her eating chick starter this AM, so I know she is getting something.
