3 Silver Laced Polish Bantam Mix Started Chicks NPIP

I have 3 Bantam Silver Laced Polish Mix Chicks Started. They are 4 months old. These are unsexed. Not sure what there mixed with they came from a guy a bought my polish off of and he must have had them cooped up with other chickens and I didn't know and started incubating the eggs as soon as I got them.
