I have 1 bird that has a daily swollen crop. She acts completely normal but look like she is about to burst by the end of each day. When I let her out of the coop in the morning it is completely deflated and she is eager to eat. She has access to grit and "free ranges" in our small backyard so she has access to her pellets and plenty of grass, fruits vegetables grass etc. When I feel it I can feel whatever she has eaten. Example this morning I could feel the small amount of scratch she ate, by the end of the day its mushy because she eats mainly grass, veg and fruit. She has lost some feathers, She is a sizzle so her feathers are crazy (shes a fugly lil girl. She seems to loose them , then fluff up a few weeks later. Should I worry? None of the other girls have this.
