A mix of ones from her 'sisters.' I removed a small one from under her, left the others and added 2, ones from my welsummers. Her usual nest got 'occupado' when she was thrown off the nest by me, and it was a girl she is below and couldn't evict, so she hopped in the next-door nest which already had some eggs in it - laid that morning. We will see what happens - she brooded 2 years ago and was a good mom - but she never went brody last year.
Good news is she just bought herself a permanent place in my flock if she hatches again. (Instead of going to freezer camp this fall.).
I didn't tell you all, did I, that I have 17 littles? I can't upload pics since the computer doesn't recognize the camera anymore - but I had ordered for March 12 heritage BRs and added 3 Welsummer pullets to round the order to 15 (the Welsummers were actually free - the three cost less than the extra shipping would have been for an order under 15!

). They had a max. order of 5 Heritage BR pullets and 5 BR straight run...and I added 2 Heritage BR roos. They are now 7 weeks old - the Welsummers are fully feathered, the Heritage BRs still have a bit of the baby fuzz on the back of their heads/necks. The boys are becoming quite obvious with the lighter barring (more white in the stripes than the girls.). Of course, the two 'extra' chicks they sent were boys, too. I want to set up a breeding program with them - so need a min. of 6 girls and 3 boys - I was hoping for 8 girls and 4 boys so I could use some selection to keep the best 6 girls and best 3 boys for the breeding to keep genetic diversity....3 trios, boy A mates with Girls 'B', and boy B mates with Girls C, and boy C mates with Girls A. Young stay in Mom's group - this keeps some diversity. The goal isn't to become a breeder per say - it is just to be able to keep my own flock in perpetuity without having to 'buy in' new chicks all the time.
(Maybe once in a while for new genetics, but not on a regular basis.)
Anyways - the chicks are so cute - and I have been for the past week fencing off a portion of he run adjacent to their brooder coop so they are safely mingling with my adults. Soon, I will be releasing them without the protective fencing - but with a 'block' insert on their door so most adults can't get in and harrass them (if they. need an escape) nor devour their food. I do have 3 leghorns from the 'surprise/mixed' group I got last fall - and they are so slight that they will probably be able to get in - but not my other, fuller bodied girls.
