Red Ranger 50g is a Med egg, I have a sizing chart that states anything over 49.0g is med.
I have found most my eggs are getting a bit bigger, the EEs are supposed to lay med eggs in general for their breed. I still get some 30g eggs (yes 30g) and have gotten some well over the Jumbo size of 71g, but in the past 6 weeks since my girls started laying I am seeing more 50-53g eggs than the 35g that I was seeing.
I can't believe that it has been 6 weeks since they started laying. I am consistently getting 9 eggs a day with the occasional 10 or 11 eggs. I sometimes wonder if all my girls are laying, I thought I would see around 12 or 13 eggs consistently if all were laying. They all have red combs, and I think they all squat but some run for the hills when I enter the coop.
I don't seem to have problems with my girls sleeping in the nest boxes, but they had a perch almost as soon as they popped out of the brooder. I also did not make the nesting platform until they were 16 weeks old and it was only the last month that I added my buckets to the platform. I swear my coop is always in some state of construction.
