Coop caught on fire from a heat lamp. I lost 3 chickens. Other 4 are singe and sooty looking. Feathers are kinda burned and singe. What should I do to help clean them up? Like around their faces, eyes, nose. One chicken is still in the process of molting and she got singe too. They have ashy/smokey feathers. What should I do to clean them up? Should I put vitamins in their water to give boosts of energy? Should I give them laying feed, or when should I? Thanks so much!
