I don't have a vet nearby that deals with chickens much less one open on a Sunday. Buffy got her head caught in the nest box Friday so I thought that was her problem, but she's still not standing up--just crouching and not really eating or drinking. I separated her yesterday and she hasn't pooped in over 24 hours and her food and water are barely touched. She stays head almost on the floor and back end kinda up. I took a latex glove and felt in the vent. It feels like what I THINK are tiny broken pieces of the shell. It feels crunchy. She regularly sits in the nest box for extended periods of time, but I thought she was just broody and thought nothing of it on Friday. I should note that I have 8 hens less than 1yo and on Tuesday is the only day I have ever gotten 8 eggs--so I know she laid an egg then. I've given her a warm bath. When I go to check her vent, it looks like it's pulsing...? Is that the right word? And if it matters, her comb looks so much less developed than the other hens. Significantly. She was hatched the same day, but she looks at least 2 months behind in that respect. Not sure what matters here. There's no egg white/yolk on her feathers near the vent but in the warm bath it looks like a tiny bit of that stuff came out (and semi-congealed in the warmth of the water). So she's been this way since at least Friday. I MIGHT be able to find a vet tomorrow, but the hospitals I called today said they wouldn't know what to do. HELP!!!
