I have or had 2 Welsumers and 2 Buff Orpingtons that were doing great. They have been in their coop for about 2 weeks. I live in New Orleans, LA. Everything has been going great. When I went out to check on them this afternoon, one of the Welsumers was dead, face down in the run. No signs of being sick. She was perfectly fine this morning. No one else seems sick. I am concerned that I missed something or am missing something. No signs of injury. Any ideas on what I should look for? My coop does not get a lot of direct sun. It rained yesterday but they are well sheltered. They have been enjoying their new perches inside the house. Any ideas why this happened? I am worried about the rest of the girls. thanks.
