I put them out in the run 2 days ago in a temporary brooder with heat lamp to let them get aquainted with my (6) 5 week olds. They were out there 2 days and I let them out in the run a few times and locked them in at night. I kept tabs on the temp in the brooder and it was stable at 87 degrees day and night. All seemed well. They were having a blast running around and playing. Yesterday I noticed one was a little lethargic and by yesterday evening they were all huddling puffed up and not moving around much. I brought them back in the house. Gave them vinegar water and some yogurt, but they don't appear to be eating. They sleep all the time. Now I need some guidance with supportive care. I have some liquid b complex but I don't know how much to give them. I have the yogurt and the vinegar water. Should I be forcing fluids in them now. FYI their poop looks fine. One baby had one that was watery but then had a normal looking one just a little while later and I havn't seen any blood. My 5 week olds are healthy as can be. Thanks.
