Maggie is a Batam hen around 18 months old. She not a good layer, has routinely had soft-shelled eggs even with added calcium-she never lays routinely. My first thought is that she's egg-bound. She doesn't appear to have a egg (or pieces) in her vent. Her poops look ok. She ate well yesterday. This morning, she was on the perch, would not come down with the others, and she allowed me to pick her up without her usual mild protest. I brought her inside to a cool and quite place. She doesn't seem to have any eggs (lumps) in her belly, or any bloating. Her crop feels empty. I've been giving her a few drops of water every half hour. I started her on probiotics and tetracycline (McMurrays's Grogel and Ornacycline) placing bits and pieces in her beak. I do not know how to crop-feed. I've been looking at posts all morning to try and glean some insight as to what is wrong with her. She is currently resting with eyes closed. I have my flock (1 rooster and 6 hens) on scratch, laying mash, oyster shell and granite grit, extra calcium as needed, fresh corn and other fresh foods as I have them available---same diet for a very long time. They've been in their winter coop, that is 'inside,' (due to snow and cold weather) for 10 days but when the weather inproved a few days ago, I let them out in their yard. Everyone else seems fine. The older hens are not laying, but the others are without issue. I deworm them in the fall. I keep a clean chicken house. I woud appreciate any advice or suggestions.
