One of our hen trio turned out to be a he and we couldn’t keep him. Of course, he was the favorite. The other two are 12 and 16 weeks old. I have a very large brooder with an attached “play pen” for quarantine and the coop (when finished) will be 4X8 with a 72 sq. foot covered run. Chicks are being put in the run during the day now but come back to the brooder at night. That routine has gone on longer than expected because of the crowing. Very soon the two remaining girls will stay out for good. FYI – the run is weather and predator proof. I know for sure one of the chicks is a she and the other I’m pretty confident is. Maximum capacity for us is 3 egg layers and 1 very special retiree. We really don’t want to start over with baby chicks but I’m unsure about the right age/combination to get for this set up. Craigslist hasn’t been too helpful in finding a couple pullets locally. And to be fair, I’m a little particular about what I want. Is mail order the best option? From where? Would it be fair to keep older chicks that were probably already on grass in the brooder for a few weeks?
