We decided to get some eggs that are starting to hatch. 1 chick hatched last night and we have 5 more to go. My question is we are making a temporary area because the way our chicken coop is was going to be difficult to chick proof so we made a small yard with house for them but I'm worried about the cold. We live in San Diego and it's been getting down in the 50s and Momma hen seems fine but will she be able to keep them warm enough?
