I have never in somewhere around 2000 keets hatched had a keet with an impacted crop from just over eating on starter feed (dry, not even fermented)... are there whole grains or scratch in your FF mix? Are they on shavings for bedding? Keets cannot digest/pass grains or shavings, but will readily gorge on both... so either could cause an impaction. It may be lower down, than being just the crop, and could be backed up all the way to the crop. I'd keep up the EVO, with some molasses mixed in, light/gentle crop massages and plenty of water... I'd also separate him into a small shoebox or another similar small box on the edge of the heat lamp light glow with a stuffed animal to snuggle up to/under, and a mirror. I'd withhold food for a while until the crop empties, and if they are on shavings... get them ALL off ASAP, and back on paper towels or shelf liner immediately. Keets are bad about eating shavings.
crop has gone down some this AM so that's a good sign. He's been pooping well over the past 12 hourse, and I firts noticed the crop to watch 24 hours ago, so I doubt that he's too backed up. I have him seperated so he can't get into anything except water until his crop empties. I will add molasses to his olive oil this AM and give him more gentle massages. They aren't on chips, I figured they aren't old enough yet? I have a piece of sod in there for them, as well as paper towels. everyone else seems ok, so I guess maybe this one just ate too much grass?? they have acess to chick grit and seem to be eating it, I've sprinkled some on their food as well. I grind the FF for the chicks pretty fine myself, it's about the consistancy of the starter feed.
at what age can you put keets on bedding? (I use shavings/chopped leaves in my bigger brooder.) without them eating it? opinions seem to differ.
