I am the proud mama of 2 barreds, 5 rhodes, 4 sex links and one unknown. supposedly they are 12 days old but they have tail andwing feathera, combs and are flying. i am assuming they are older but how old might they be? Although i tried a mother hen cold brooder they didn't really like it. We ave been keeing our house at about 75 and they are perfectly content without a heat source. Our outside temps just hit 70 and i was wondering if it is to early to take them out for small play periods.
