They were hatched out by a devoted Silkie chicken and she's been trying to be a good momma, even though this is her first time hatching out anything. Tonight though, it got down to 52 degrees at my place and the ducklings were not under her when I went to check on them before bed. They were huddled in a dark corner of the coop on wet material. I gathered them all up and made a sad decision to take them away from the hen, for now anyway, and have them spend the night in my chick brooder where the temp is always 80 degrees. When I went to gather them out of the coop, they were sluggish, and they were peeping more quietly than usual. I'm really afraid they've gotten too cold and will be ill. Should I administer a little sugar water? They are in a brooder with chicks of various ages. I don't want to throw them off, but do want to make sure the ducklings get what they need. Thanks in advance for any advice.
