Dirty eggs

Hello All, I just ran into a problem I've not had before. I have all of my breeders in roll out pens I've made and the eggs stay real clean til now. Is it that maybe I changed feed on them and it made the poop runny or make it stick to the cage floor I dunno. I've been spraying the entire rows of cages I got with Tek-Trol every so often and not in a week or so but I've not had this happen before. I'm gonna go out there tonight and spray everything down really good I'm hoping it will fix it. I had about 32 culls(dirty,tiny,odd shaped) last week and I get that much just from a few cages as I gather them. My eggs are EXTREMELY huge I wish we could get these size eggs when we had to order them but our eggs are huge they compare to the coturnix BIGTIME. I've fed them the very best we could get and they've never came out this huge and now their dirty so I've got A LOT of eggs to put in my "cull incubator" even in it I'm still getting great hatches. I have the drink-cup watering system and the front trough feeders so no way to get the eggs dirty. I hope I can give them a good dosing of Tek-Trol and it'll fix it I won't know til tom. I hope ya'll can give me some pointers as what I need to do I've wasted a lot of eggs this week.Thanks, and GOD BLESS,Tommy
