We are on day 18 of my broody sitting on a nest of eggs. We started with 12 eggs and we are down to 4. We candled day 10 and 3 of the 4 looked viable. I wasn't sure about the 4th so I left it. Momma hen has only left her nest long enough each day to do her business and has done well. She's overly protective actually! I've been gone from home all day today. When I left this morning she was in another nesting box and another hen was on her eggs. This has happened multiple times during this process (usually while she is out and another hen chooses her nest to lay) and I just remove the newly laid eggs each time. Eventually she always gets back on her nest. Well today, after being gone over 6 hours, she was still in the box I saw her in this morning. Her nest had her 4 eggs plus 5 laid today. All the eggs were cold. I'm in Texas and it's 33* right now. Have I lost my chicks? For 5 eggs to have been laid in that nest today I know they haven't been exposed all day long. But they are all completely cold. I took out the 5 eggs laid today and put her back on the nest. I'll check her soon to see if she is still there. I don't have an incubator but I can get one from a neighbor if she abandons again. But I'm curious if the exposure today has killed them?
