I have raised day old silkie chicks on my own before but this time I'm doing it naturally with a hen and I'm not sure about a couple of things. 1) Bedding: I prepared the cage with paper towels on the 1/2 with food and water but I still need something for the hen to lay on. She has been laying on the eggs with a nest made of timothy hay. Will the new born chicks be OK on that surface? 2) Do I need a lamp on the cage if there is a hen? They are in the garage and the temp is no lower than 55 at night. I put the lamps on them today since the chicks are already starting to hatch but I think the hens were too hot so I turned them off.
