We introduced the chicks today, and were pleasantly surprised to see that most of the 2.5 week olds get along beautifully with the 3 day olds. They are cuddling with them, and the 2.5 wk Silkie is actually nestling in amongst them to keep them warm. Even the gigantic Welsummer is being very sweet, as is the hamburg - very nice! BUT... The Mille Fleur d'Uccle is absolutely vicious with the babies. I know you're probably thinking "uhhm...a vicious d'Uccle?" Yes, she's very nasty with them. She'll grab their beaks and run off with them attached to her beak. She'll grab them by the butt and run off with them, and she'll get a hold of a wing and yank really hard. She's the only one of the 2.5 weekers that do this to the babies. She does it constantly. I separated her from the others for four hours and they were peaceful and sweet to each other. The second I put her back in there - she goes after them with a vengeance. This doesn't seem like "establishing a pecking order" to me ...it seems like she's a cold-hearted little chickacidal maniac. what to do?
