I just went out to clean the coop this morning and found 4 day old chicks huddled in one corner in front of the nest the hens in. She still sitting of 2 more eggs. My question is should I put some type of a heat source in the coop with the chicks not under the mother or just trust her judgement on the chicks needs. There is a about a 3 or 4 inch board for them to cross to get back in. They huddled up and peeping away. Thanks.
