I was feeling one of my cull roosters yesterday, wondering how he would look all dressed out, and noticed that his crop was half full, felt kind not right. Some of the other birds in the pen felt the same, some better, some worse. I gave them some potato skins, lots of watermelon lately, but otherwise than that, they are on free choice Start 'N Grow crumbles and layer pellets, with clean water always accessible. They are on a dirt floor that I spread out some composting straw on last week to aerate by hand and let them pick out some worms, mix in their poop, wet down with a hose and put back in the barrel, but that's about all they have had. Oh yeah, they also have free choice to the oyster shells. Any idea what is making their crops thick and pasty like that and what do I do about it? Any help appreciated. Is it possible to place a tube down their throat and irrigate it, massage it and pull the junk out if I was so brave as to try?
