I posted before on this and didnt get responses but one. They are 6-7 weeks old, not under heat anymore, outside in coop at night, run during day. temps at day are 60-70 and at night 55-60. sleeping on sand, they wont perch yet, in coop. they eat purina frow and start medicated and little scraps. First the BA feet thin, the underside bone and meat around it. Now the EE feel thin. Feels like they are loosing weight. The EE are usually very robust, heftier. They seem healthy though, they eat/drink/poop normal. So searching I can find nothing. I see no bugs on them. Do they need something else to eat that helps with weight?...or is something wrong? Sorry, I am new to actually owning chickens. Taken care of family/friends but never raised them myself. Any help would be appreciated much.
