I'm hoping for a little help. I have 17 hens of various breeds most are brown except for my 2 brown leghorns. Over the past week to ten days I have not been getting white eggs. Is this natural? Do chickens take periods of time off where they don't lay? All my girls are 7+ months old and have been producing excellently. I have looked around to see if they are laying outside the nest but haven't found any evidence of it. They get free choice oyster shells, fed layer crumbles and kitchen scraps. They have a covered area for outside ranging/playing. The only thing that I know is different is that I haven't been able to clean out their coop area. Could this cause them to stop laying? Any ideas/help would be greatly appreciated. Should I quarantine my leghorns and keep them away from the others??
