I was just about to put out our 7wo chicks in the run and noticed fuzzy white stuff all over the feed that had been spilled in the run(grassy area fenced in).It had rained. I quickly made an area for them with bamboo stakes,plastic fence,and zip ties. Now the question is how do I clean up all the moldy feed in the grass and make the area safe for the chickens? I have raked and picked up what I could.Should I spray with bleach?Water the area over and over?Keep the chicks out of there for a week or 2? I can put up the fencing in various areas,but this little spot was perfect by the big hens and the kids pool.I could keep an eye on everyone from this one spot.
