We just adopted two Silkies. The owner said they are ten week old pullets. THEY ARE TINY. I have two 13 week old cockerals that are literally 2 1/2 times as big. My cockerals look full grown and these pullets are as big as the cockerals were at 4-5 weeks. Is this normal? The guy said that he had been feeding them layer pellets. Do they just need some TLC - and some starter feed!?!
