thanks! i'll try that -- and i'm not sure of the exact ages of the new birds (i seem to be settling on the names Frances and Bella), Cheryl just grabbed two that seemed to be similar in size to my previous flock -- three of whom are 8 weeks old (Daisy must be younger, she's still so much smaller), so best guess is around that. Frances & Bella are a little bigger than the others (esp. Frances), and MUCH bigger/stronger feet (they both scratch the ground like crazy, which is great!), so maybe 9 weeks?
next month i'll be getting four additional baby chicks (two cream legbars, two lavender/blue orpingtons), which of course will start in a brooder, but i have the feeling i'll need that pen to more gradually introduce them to the big girls once they've grown enough...
best,
laura
