When were they spayed? It took about 2 months post spay for my girls to improve. Have they recently arrived/or their accomodation been changed? Territorial marking can account for a lot of stray poops. Is the tray large enough for them all to sit in at the same time? I like the underbed storage boxes for trays as they are larger and have higher sides than cat litter trays and stops them from spaying over the edge. Do you have plenty of hay in the litter box? They like to eat and poop at the same time! You may need to provide more than one tray. Sweeping up poos regularly and putting them into the tray would help too. Also it would help if you have just Lino/rubber floor or similar on the floor of the hutch, and only have the hay and newspaper or wood pellet cat litter or similar in the litter trays, it's less confusing for them :thumb:
