Our Silkie hen has one chick (4 days old) so far (she's laying on another 7). She and her chick and eggs have been in our garage with 250w heat lamp above her for about 1 1/2 weeks now. Everything has been going as it should be except I noticed my hen threw up water and then her chick drank/ate it immediately after. Is this normal?? I have never seen my hen ever do this. She is acting normal and so is chick with the exception that she likes to sleep huddled up against mom and not under. I'm wondering if that is normal as well? As all of our other chicks in the past laid under. I'm probably over thinking but just want to be sure. Thanks!
