That was why I got BO's they were nice & chunky, and were said to be great layers. I have 6 who were born the first week of May, as were my 3 BR. I know my 3 BR are laying every day, I can tell them apart by size & beak color. So with 9 hens all the same age, and my 3 EE, 2 weeks younger, only 2 are laying almost every day & the other every other day. I should be getting at least 10 eggs, but am getting 5 - 7 eggs. So I know some of my BO are not laying.
OT, would using some of that Halloween wash off hair dye on them (just a spritz) cause the others to pick at them. I would like to spray a spot on the BO as they leave the nesting box after they lay, just to find out who is not laying yet. I know 4 of the 6 are laying, but if I could find out who are not the consistent layers, sell them & get some in the spring who are good layers.
I enjoy a mixed flock, it is easy to head count while they are free ranging or at bed time.
Am no where near to being an OT, but I do run & free range. They are in the run about 1/2 the day, until my youngest gets out of school, and if I am going to be home, they get let out in the yard. The only time there is a fuss, is when our roo, Owl gets frisky, first thing in the morning, or just before bed time. But knock wood, no feather picking, they have been in their run for almost 6 months. In the spring I am going to expand their run an additional 10 x 10 off the main run, it will encompass the oak tree, and provide more shade for them this next summer.
