My newest flock additions are 10weeks old now. Everything quite normal, they've been in my very dry brooder room with attached little outdoor run. Diet is only All flock crumble, nothing else. I have not treated with Corid as I have not seen any signs of Coccidiosis. But my cute little blue feather foot, Blue CM has had a big, squishy, not emptying over night crop for about a week. I've massaged it a little, hoped it would go down eventually but it hasn't. And this morning I noticed her stretching her neck/trying to adjust. SO I'm actually thinking instead of treating for crop issue, I should start Corid. What do you think? I remember a thread with experts a while back where the advice was to start Corid incase this all about a heavy worm load. And then if that does not help resolve the crop, treat for sour, impacted or doughy crop (I forgot to go smell her breath, I'll do that now.) Is this what you'd do? Or would you treat just as a crop issue? Also is this a Maran's thing? My adult hen BCM has always had big swinging crop but it does empty right about the time I start getting worried....
