Hi, I was wondering if I could put ducklings and chicks together. I have one pen that they cannot get out of and wasn't sure if I should rotate them or if they can go in together. Right now the chicks are still using a lamp at night...not sure when to stop this. The ducklings stay out all night in the pen with no lamp. First time having ducks and still new at the chicks. Any answers would be greatly appreciated!! I bought both together almost two weeks before Easter but the ducks are bigger than the chicks. Thanks A Lot!
