how early should I give my babies de wormer or is that a big girl thing? also I have a litlte Australop prob about three days old. She is sleeping under my older (3 weeks) cochin and cuckoo maran. Do I still need a light for them? They are either sleeping together or on the little roost. What happens if they get to cold? The last bunch I had 2 years ago we had to keep the heat lamp on for a long time because they were all 3 days old and it was winter time. Right now they are inside with the top and side covered up at night.
