Hi everyone. We had a huge storm this arvo and have no power or way to get hot water. My silkie chicks are around 3 weeks old and have most of their feathers - how long can they last without heat? It will be getting down to 16c here tonight and they are in the warmest part of the house in a plastic tub to keep any heat in. There are 3 in there so I don’t know if that is enough body heat for them.
