I went to close up my hens coop last night and found my Australorp hen not up on her perch but down below in the dirt. She is my top hen so it is unlike her to not be up on the perch with the other girls. She drank quite a bit of water so I let her be and when I checked again in an hour she was in the egg boxes. She never sleeps in there so I brought her inside. She hasn't eaten, or pooped in 9 hours. I have checked for an egg via her vent and couldn't feel one but when I massaged her belly gently it feels like there is something there. I have given her a couple small pieces of calcium by dropping them into her beak because she won't take any food or treats. I tried the warm bath as well but couldn't keep her in the water for the suggested 15 minutes. She'll stand for a time then lay down. She's never had an issue with her eggs so I'm stumped. My hens get a good layer feed and they also get eggshells. I feel like I'm running out of time. There isn't an avian vet in my area. The closest one is 100 miles away. Please if anyone has any thoughts or suggestions I'd really appreciate it. She's also going through a molt.
