I am taking care of my neighbors chickens for 4 days, and they told me that they are receiving 3-4 eggs a day out of 8 hens. I looked at them tonight when I was shutting them in their coop, and some of them look skinny and don't have the shiny feathers that I would expect this time of year. I'm going to check them for lice tomorrow, but is there anything else I should look for or try? I plan on giving them some oatmeal and yogurt to help them out, but would really love some advice on this. Thank you!
