A little bit away from the topic - but a question you may be able to answer. I had a single chick hatch -- and went to the feedstore to buy a companion for that chick to grow up with. All the other chicks I have are 2-weeks older to about 9 weeks older.
I bought an OEGB - and the information I found says that they tend to go broody, be good mother hens and don't lay many eggs. -- If (and I hope I picked out a she) were to go broody, how many full sized eggs could she cover? Size from research says these hens will reach 20-22 ounces. Little! Wanted to make sure that the new chick I got wouldn't beat up the 2-day old....and the now the 3-day old is bigger than this 2-week old.
Mind if I say something? I have several OEGB hens, and one is broody and on day 14 right now. She has never been broody before so I can't say what kind of mom she is. She is 15.95 oz and is covering 10 bantam eggs- not sure how many LF she could cover if she was motivated, but I have seen 3-5 under her.
