Hello everyone, im kinda new to all this. I bought 6 silkies and 4 plymouth rocks chicks, all silkies and 2 rocks are eating and coming along fine, but 2 of the rocks are not growing. Ive noticed that dont eat as much as all the others do, the kinda stand back and eat any leftovers. Today i seperated them to see if they would eat, but nothing yet. they are 3 1/2 weeks. Any suggestions?
