Hi everyone! So I have 4 chicks that are 4 weeks old in a run that is 3X7 during the day and then back inside with a heater at night. (They will have a 75sqrft run when bigger) but, we have a smell problem! The run is play sand with gravel about an inch or two bellow. Because they are still small chicks their poops are still tiny and fall through the kitty litter scooper I have tried to use. It is also a low enclosure so it is really hard to climb in and reach everywhere. I have sprinkled a light layer of DE on top of the sand but it hasn’t helped with the smell. I have read all kinds of things like just raking and never scooping out and watering the run once a week, etc... I have read many things even some people saying not to do the above mentioned - basically I do not know what I should do or what to try to help this. I want it to be a clean and sanitary place for my birds. Thank you so much for who ever can help me!
