I have 4 hens about a month apart from each other. I bought two that were supposedly laying and 2 I had since late march that were almost fully feathered. I get two eggs a day, but not always the same. I got a large with and without spots, mediums and smells. My hens are barred rock, silver laced wingotte, orpington, and Rhode island red. I'm I getting all hens laying or am I still missing some? I know for sure one of the bigger is from the silver laced since I watched her nesting on it one day. Is there a way to tell who is laying?
