Just got my first egg from my 6 whiteleghorns at exactly 19 weeks old. My question is when can I start throwing in table scraps and chicken scratch? I have grit out now but is it time now to put out some shell? How much/how often can I give them scraps and/or scratch? Also I have 3 domoniques in with them that are 6 weeks behind in age. So will scraps and scratch hurt them at this early age. They are about 13 weeks. Please advise of ANY scraps I SHOULD NOT give my chickens!! What can they eat? Is there a list of do's and don't somewhere I'm missing? I'm just excited to get my FIRST egg!!
