Hi Tracy, yes post away

There is nothing better than Ross cob for converting food to meat and you will have plenty of chicken dinners next year that's for sure, but they are not what you would class as self sustaining!
Are you looking to breed from them?
They are the end result of various hybrid crosses and are not created to be bred from as they become too large for their legs to carry them, but people have done it with an extreme controlled diet.
It also keeps you going back to the suppliers.
What's your plans?
