advise needed re; peeping chic please

[goldenchic]

i have 2 ten month hens, and wanted to add 2 more so i bought 2 more chics on saturday their 8 wks old.i have them in a seperate run & coop inside my big run, so the new ones can be seen by my old hens but cant be hurt, ive been watching them my little booted bantam keeps constantly peeping & trying to get under the other chic at times almost knocking her over,when i picked her there was about 20 chicks in the pen is she missing huddling? how can i help her

Maybe she's cold. Put a light out there so she can warm under the light. Just a thought.
