I have 10 new chicks (and 9, ten week old chicks) One of my new little ones (2 1/2 weeks old) is very small. She is a partridge rocks- I have 5 total PRs and she is so small- my other ones have feathered out a good bit and are growing quite nice (not as rapid as my RIRs- but nicely). However, my one poor girl is not growing much. Although she is very happy, eats a ton, drinks a lot and is over all active. Can she be a midget chicken? I see no signs that she is not healthy- she is plump and happy- but my goodness a small thing. She looks like she is maybe 1 week old not 2 1/2 weeks old.
