5 month old buff orpington. Has not layed an egg yet. One from her group has been laying for two weeks. Last 4-5 days, been quiet, stays away from other hens. Seems depressed. Feathers look ruffled all the time. Eats a little if I put in front of her. Has extremely bright red waddle, comb and the end of her beak is red. Is in the house now - as I was afraid it was a heat stroke. Not steady on her feet. Lays with her rump up and seems to be straining slightly. When she try to walk will stumble and fall over of backward. Eats a little fruit, vegs, crumbled. Have given her vitamins B, D, Selenium, chick pedialite, and save a chick, in her water and vitamins in her crumble. Could she be egg bound? Cannot feel an egg. She feels light compared to others. NO signs of respiratory issues. Have lost two others - and thought it was the heat???? (within the last two months). Crop was half full this afternoon.
