Awesome! Glad to hear it's going well.
My 8 are surviving and the little ones are now starting to hold their own =) They were playing keep away with some cabbage from the 12wk olds.. Looks like everyone is getting their share of food and water since I added more feeders, too.
I am going to try your merging idea tonight, with the coop. The babies go in on their own now at dusk, and the 3 older girls stay down (fortunately we have a dog who loooves to keep them safe). I am going to add the more docile 12wk old to the coop tonight. They seem to do well in the run, all mixed in. I am anxious about the coop, though (since it is smaller and roosting takes place).
Just curious, though I know it doesn't go here- do you have a pic of your girls? =) I'd love to see them!
