Hi this is my first post and am after some advise, I have a RIR hen who is roughly 2yrs old, we rescued her 3mths ago along with 4 others, the are all ex free range layers. She has always looked poorer than the others not as shiny, pale looking and recently has lost a lôt of weight. Thursday evening she was puffed up, eyes closed and not happy, we have since put her in the hatchery under the heat lamp, she is drinking and eating but not an awful lot but is looking brighter but still not right. She was laying but stopped a few weeks ago, not egg bound, mites etc there was an egg without the shell laye 2 weeks ago but have no idea if from her or not? All others seem fine?! Any ideas or anything I can give her to try and perk her up a bit or any weight gaining food I can give her? Thanks
