Aw thank you. It was hard, but it was indeed the right thing to do. I may just be content with these two for now, see how I do as a chicken keeper before adding to the flock. I can't really order more Sussex because everyone seems to be sold out for the year. Maybe in the spring. But to answer your question, the min. order is 3 and I doubt they would throw 2 in free (not like a chick is a huge expense though). That would make 5 chickens with all those eggs and there are only 2 of us. I'd be giving eggs away left and right!
I'm so glad your babies are doing well! That's so cute that they fell asleep in your hand. Mine chirrup and run away, but I persist and pick them up for a cuddle. They do eventually relax and close their little eyes. One of them has lots of wing feathers and has been practicing flying and keeps looking at the open top of the brooder, so I found an old window screen that fits perfectly. There's a big gap under the door where their brooder is and I have two cats, so the last thing I wanted was an escapee who became a midnight snack.
I found a small stick today and put it in there because they were perching on top of the feeder and pooping in the food. Since the stick is a little higher, that seems to have done the trick. Such funny little creatures!
