Hi, hoping someone can help me. I have 8, 10 day old Silkie chicks in a brooder using lucerne chaff as the litter, medicated starter and water. One of them has a large crop, it is pliable and if you listen carefully when you gently massage it, it seems to have some air in there too. I took the food away from them last night and this morning this little one's crop was still full. Could it be impacted? if so, is there something I can do for it? It seems normal in every other way. Thanks.
