Have 12 birds. 7 pullets, 3 roosters, a Barred Rock and a Black Austtralop. The BR & BA are older hens from a friend who was going to slaughter them. The were laying quite consistently when I introduced them to my flock and continued to do so within my flock. Due to my birds roosting on there nest boxes and my built in brooder box I realized through posts here that I had my roosts too low. Since changing their positions my other 10 birds will not allow them to roost on the new roosts. There is more than sufficient room, it jut that my original 10 will not let the BR & BA roost with them. In turn they stay in the floor at night. Since making this change they've not layed any eggs. My question is does then. It roosting properly affect the laying process? A few of my biddies!!!
