I was just thinking last night, I know..watch out that can be dangerous! lol I have BCMarans and I want to figure out which hen lays what egg. I would love to be able to do the trap nest, but living in Tx, its too hot to do that. I remember watching a PBS show once about a dairy farm that tags and scans the cows. When they go into the stall and get milked it scans each cow. So they know how many times that cow has been milked and how much milk she has produced, etc. I wish there were some way to do that with chickens. Cause I dont know about anyone else, but I dont have time to set out in the coop ALL dang day to see which hen lays what. I know, Im dreaming..
