What my thoughts are: If I have say six of them then I could put a couple of groups of young in each one as grow out pens. I even thought of making a few 3 x 6 for cock bird pens when breeding season is done. I have a few boys that stay together well without fighting and a 3 x 6 would be plenty big enough for 2 adult boys. Oh my, it seems we never get done with these birds. I would never advise anyone to get more then one line of reds at a time. lol It sure is a lot of work. I wouldn't mind if we didn't go below freezing during winter time. I just hate breaking all that ice every day. Geez, it seems like I do an awful lot of complaining. ha,ha.
I'm already snowed under trying to keep different Nelson lines separate and if I added another line I'd be really scrambling, I have to build this stuff for them myself and some of it is not much to look at but it works.
