So I had a buff orpington go broody and my 8 yr old son was really wanted her to hatch some chicks. At the same time I had an almost wild leghorn go broody and sit on a clutch OUTSIDE where she got rained on more than once. Anyway eventually leghorn gave up so I added her eggs to buff orps clutch. THEN a few days later errant leghorns DAUGHTER started to sit on eggs with buff orp as it was now a LARGE clutch and they would releive each other so they could go get food and water. So they started hatching on friday, I currently have 5 and will have more I am sure. SO buff is now sitting on eggs and leghorns daughter looks after chicks. BOTH are caretaking of chicks. I brought food and water in coop for orp. She told babies to eat/drink. No today the oldest 2 are 3 days old and leghorn daughter took them outside coop. Other 3 stayed inside under buff. Then leghorn daughter brought chicks back in coop and both hens will allow babies to snuggle under them. It beats all I have ever seen especailly since thIS leghorn never laid a clutch she just decided to be the aunt/ast mommy. Is this common? This is only my second hatch of home growns.
