Mother was killed last night. I have a new born chick 9 hours old. They lie down a lot. Good luck, and enjoy those babies! They have feathers that they can fluff and they sleep on their feet.
Otherwise, the big chicks can hurt the babies.
How Long Does It Take for Chickens to Mature?
In warm weather, you don't really need a heat lamp, but get a secure pen and chick starter until they're 20 weeks old. I keep my in a clear plastic tub with a screen over the top. This happened over a 4 hour period of time. I let the dogs out to do their business just before I let the girls out. The question is should you kill a 7 day old bannis rooster just because he fought with another one his on age.
