Wow! Thank you for all the responses and welcomes to the board! This is just such a great site. I'm sure I'll be spending many hours reading and learning from the articles and this forum.
I am so happy the other 2 are hens! And it's also nice to hear they may be young yet! So far, no eggs, so besides finding themselves in a new living situation, maybe it's more due to being young.
Isn't that strange someone would drop them off then?! I was expecting that were all roosters in a way, just because I can see where someone may want to cut down on roosters... But I still can't see just turning anything out like that. I have the word out I found them and have asked all the neighbors and they all think they were just dropped off, so I'm really hoping no one claims them! haha!
The 2 large ones are somewhat tame and the little red one is faster and a little more leery of me, but it's only been one day, so I'll keep trying to handle them. I'm just glad the rooster is calm and not aggressive to me, so I'll try handling him a little too.
Now I'm off to go study up on the breeds and the chicken coop plans you have here. We will be getting some cold weather soon, so I'd better be ready!
Thanks again for all the great info!
