Hello all...I apologize if this has been answered. We have 3 Plymouth Rocks (1 Barred, 1 Partridge and 1 White). Our White girl "Peep" went broody in July and a lady from our local Tractor Supply gave us some eggs from her flock to try hatching (we don't have a rooster). She had advised us to let "nature" take it's course and that mama would protect them if the other two girls got too interested in the babies. This sounded like good advice and we were all set to go with it...today our eggs started hatching and we have 4 adorable little chicks (so far anyway)! I ran back to TS to get some crumble for the babies and the guy working today said that I absolutely must separate the chicks and mama from the other two birds. This won't be an easy task in our coop (12' x 4' with a completely roofed and hardwire clothed run, and nest/roost area above that with a ramp up for the girls that is completely enclosed.) I can close the door to the upstairs to keep the other 2 out...it is warm here and they could sleep in the run...but I doubt they'd like that much. Mama went after our 120 pound Great Pyrenees when he stuck his head up there to say hello to her and her eggs a few weeks back. I'm guessing if she can take a big dog on that her "sisters" won't be a problem, but now I'm nervous. The other two free range in our fenced in yard all day and seem to have little interest in their new housemates. Thoughts? Suggestions?
