The average size of my silkies The little guy The rest of my chichi's(the adults are the lighter colored chickens at the top) My little guys are a little over 4 weeks right now, I have one that is exceptionally small(about half size) the rest are the size of the one with my 4 month old kittens. When would be a good time to introduce them to my flock? right now it is getting down to freezing at night so they are inside but without a heat lamp (stays around 60). I have about 10 2.5 month olds(barred rock ameraucana cross) in the coop and 2 bantam adults(ameraucana and Brahma, ameraucana is brooding right now). So all the chickens outside are about the same size now. What do you think?
