It seems that around this time of year we always have one chicken that gets puffed up, is lethargic, non-social, not laying. We lost the first one, we were able to save the second one, and unfortunately lost one this past night after days of trying to nurse her back to health. I treated her for both impacted crop and also in case she was egg-bound. Soaked her in warm baths, vasaline around the vent, checked for an egg but did not feel anything. I read on here to feed her coconut oil and then massage the crop since it was not draining. It was not hard and she did not smell but it wasn't emptying. We also gave her Calcium citrate with Vit D. I am just not sure what is happening. The food we feed has enough calcium in it that we do not need to supplement (supposedly - according to the local food mill we purchase feed from). They all went through a molt around Oct/Nov and production slowed which is normal, but no soft eggs. We increase the protein in the feed around this time. I am not sure if it is a lack of calcium. If we should be adding liquid calcium to their water? If the issue sounds like Cocci and there is a medication we should be doing? I try to keep things as natural as possible but also want to make sure our flock of (now) 17 is healthy. Please help. Thank you.
