Would be great to know your thoughts on what these hens are - they appear to be all heinz variety so crosses. They have all only started laying eggs about 6 weeks ago. I'd put them at around 30 weeks old - my black rocks in the background are old girls now - all around 5 or 6, so i'm starting to introduce younger hens into the flock. This one lays pale eggs - It is whiter in colour than the photos and VERY big... This one lays light green eggs and is more grey in colour than the photos. Quite a wide hen This one lays brown eggs and is generally a large stocky hen!
