Hi all... I'm raising my first round of backyard chicks. I had one Rhode Island Red, one Plymouth Barred Rock, and one white bantam silkie. They are a little over four weeks old. It's been high 70s/low 80s off and on the past week (Southern California) so when it's really warm, I'll put them outside in the coop and leave the door open for them to roam around the backyard. They've been feeling very cooped up and pecking at their box, and LOVE being outside for a few hours. Temperature hasn't seemed to bother them at all.. Well, long story short, a hawk swooped our bantam silkie yesterday right before our eyes. It was super shocking and sad but now I'm wondering what to do... We wanted three chickens and has a chicken coop that fits 3 chickens pretty comfortable according to the reviews, especially since they'll roam around our yard during the day. I'd like to still have 3 chickens in case another one dies of whatever else along the way. And for the amount of eggs I'd like to be getting.... So now what? Do I just get one more chick, but then it'll be much smaller than the other two and most likely get picked on, right? Or do I get two more chicks, raise those separately until they're ready to go outside and then have the four together when the younger ones are 6 week olds? But then I'm wondering about size in the coop.... Any advice is appreciated by this novice Thank you!
