Hi again all!! My two chicks that were not feelin good are doin better and I am lookin to put them back out with the others. They have been kept separate BUT in same shed. How can i introduce them back. My friend said they would get the crap beat out of them by the others. They all came together, but had to separate when they got ill. (about a week) Anyone know any tricks? AND how old should they be when u let them out on grass in pen?
