Last night, I left the food bowl in my chicken's coop because it has not had a proper meal for days. The next day, today, she has just been sitting there. I thought she was just full so I kept giving her water and she drinks it but sometimes she vomits when she drinks. This has never happened before and I fear something is wrong. I do hope it is nothing serious. I will keep giving her water to replace the liquids she has lost. Please, someone, please help.
