I have been using a nice insulated shed as a brooding area. I have 2 chickens (different ages) with very large crops. I tried searching out crop illnesses. From what i read an impacted crop will make the crop back up and will be full and hard correct? this crop feels more like gas or liquid more than anything else. i gave the chicken some oil in a syringe as people have suggested and i use ACV in my water. Could a lack of grit cause this? or wrong organ? They mainly just eat regular chick starter and the bigger ones get a little scratch. im perplexed! She seems less active than normal but doesnt seem ill-feeling. the other one is probably a month old or so same thing. Anyone know what would cause it beer-belly syndrome in a young pullet?
