with some being raised outdoors by Momma. Well, actually 3 Mommas! I have 4 chicks that hatched inside (the eggs were under broody hens, and when 6 had hatched, the hens decided they were done, so I brought the rest inside to finish under a heat lamp) and I would like to integrate them with the other chicks and the three hens. Do I just put them out in the pen and the hens won't notice there are more chicks, or is there a better way to do it? Should I try putting them in at night? I don't want to lose any----one of my 3 silkie chicks got out of the pen and was killed by my other chickens yesterday.
