I hatched out 12 SG silkies and they are about 3 days old. My MIL gave me a mutt egg (RIR & bantam?) to hatch and it did so today. I put the mutt in the brooder with the silkies and they silkies are going crazy over her little yellow toes. They keep trying to bite them--like they think they are worms or something! Anyone else have this problem?
