OK, heartbeat's settled into a nasal whine, so most of the panic's over!
Since they are chickens, that's a good thing and I guess I would care for them in the same way as chooks, judging from the replies.
Do they eat all the same stuff?
Can I still get my 'standards'? ( Well, I know I can, but what do you honestly think about me doing so?) I certainly cannot afford a second coop, etc.
Good to learn they can fly and escape well! My run will be repaired tomorrow.  Now, about building that coop...
