My bantam chicks are now 3 1/2 weeks old (two Welsummers. 4 EEs and three silkies) and were moved out of their brooder in the bathroom and into their coop 4 days ago. It was obvious after one week that one silkie just isn't growing like the rest and now she's hardly half the size of the other silkies. She eats, drinks and acts the same as the others but yesterday she developed a limp with her right leg. Careful inspections havn't shown anything broken or painful to manipulate and she still shoulders herself into the middle of the morning hard-boiled egg w/ veggies meal. A sprain? She jumps and flaps and dust-bathes like the rest and the bum leg is not splayed out to one side. She also plays getting up to and down off the tiny perches I've built for them to keep them entertained. If it was painful I'd assume she'd stay in the shavings. Because she is an obvious failure to thrive case I've kept a very close watch on her. I figured they'd let me know what their names are by their individual personalities/quirks/looks...and she's about to be named Gimpy...or do I need to just give her the tincture of time?
