We bought 6 cornish rocks, 2 leghorns and 2 pullets (unsure of kind) from Tractor Supply. I have lots of questions, but I'll start with these: 1.) I've read that cornish rocks die young. Should we butcher them at a certain age/weight to be sure they just don't die on us? 2.) The chicks are now about 5 weeks old. They are way too big for the tub we have them in. We are building a coop (out of our carport) that is about 14 x 14 with roost and nesting boxes. Are they too little to go into the coop right now? 3.) If we got a straight run of 25 chickens (we want Black Australorps) and we got a bunch of males - what do you do with all the roosters? Can you have too many? Do they need to be separated? THANK YOU!!!!
