I have four newly hatched chicks - yesterday. I was advised to take the chicks away from the mum, because mum still has six eggs under her - these eggs are not due to hatch for another five days - so, in order for the eggs to not be abandoned, I had to bring these four new babies inside. They are from her own eggs - fertilised by a new bantam rooster - but I did not think they would be fertile - he was so young and shy, I thought. Anyway, they have hatched - I have then inside under a lightbulb, safe and warm -when do I start to give them food and water, and can I give them back to mum after she hatches her other 6 eggs...very urgent!! HELP PLEASE!
