I have have chickens and was getting 4-5 eggs a day. Down to 1-3 eggs most days 2.. One chicken went broody one is in molt. Two of the other 3 have gotten very sporadic. Both were laying about 6 eggs a week. I had one lay an egg fart today. Chickens are free ranging. They get a lot of vegetable scraps. I was told they may not be getting enough protein. Any suggestions?
