So here is the deal. I have a flock of hens, no rooster. There are 7. Three from my original flock, four added in last spring as full-size pullets. Things were dicy but settled down as usual. I also have four chicks who are getting big and who have been banished into the chicken yard inside a chicken tractor. In the garage is a rabbit hutch, I have three little cuties who are smaller still -- about as big as my hand...over a month old. Things are getting crowded in these separate cages. I want to start combining. One of my little ones in the rabbit hutch is definately smaller than her two sisters and is giving me pause. I don't put off people feelings on chickens -- their brains are the size of a pea. I want it simple! Thank you.
