OKay my hens are now 3 months old. I done 2 things that im not sure what the cause of death of one of my beautiful hens was. I let them outside with my 2 giness and 2 ducks. All has been fine for almost a week. This afternoon I noticed the hen under the nesting boxes just setting. I changed my water and fed the coupe Then went on with other work. I came in this eve to again freshn the water up and check on everyone when I noticed she was flopping under the boxes and I picked her up to calm her and she just closed her eyes and passed. They are still on chick starter I was told to feed this until 4 months. The only other thing that was changed was there was a big water spill so I took a bag of un scented cat litter and poured it to soak up the water out of the floor. The chicken had no bleeding sores no peck holes around the butt was clean not swollen or red great color What did I do wrong here I understand this happens on farms and such just don't want it to happen again. I separated the guines and ducks and will be making them a house outside and building a fence in between. just in case. Thoughts wrongs I did?
