Hey guys, I have 2 6 week okd chicks that have recently behaving strange/sick. They are both lethargic and puffed up. They do move around occasionally, but I realized they are now feeling skinny. They seem to be eating and drinking. I started taking them outside so they can move out permanently and left them out one night and temperature was about 37F. Could that night have affected them in any way? They stopped using heat lamp at about 4 weeks and were at room temperature. Or could they have come in contact with worms? I don't want to lose them so any help would be greatly appreciated.
