I just had a Buff Orpington/Dominique hen hatch a bunch of barnyard mutt eggs. She is the first hen we had go broody. I put 3 eggs from a leghorn/EE cross hen and 5 of the largest brown eggs we had from our barnyard mutt flock under her. The roo is a leghorn cross (not sure with what) and the brown eggs could be from leghorn crosses, Dominiques, a Dom/RIR, or Dom/Buffs.
This is the sight I saw when I went to check on the eggs around lunch time today. I went to move the hen and this little yellow head popped out.

When I picked up the hen, I saw that 5 of the 8 eggs had hatched. I took the nest box out and moved the chicks and the eggs that had not yet hatched into the tote and put the hen back with them.

One of the EE hen eggs had a very thick membrane and I helped the chick out and the third EE egg also hatched. The remaining egg is one of the brown eggs. I'm going to candle it tomorrow if it doesn't hatch. Mama hen is doing wonderful, she is eating and drinking well now and she hovers over her babies like a champ.

6 of the 7 chicks that hatched so far are yellow (as to be expected with a leghorn father) but the surprise is this little grey chick. So CUTE! I love the little yellow spot on the chick's head.
