Update ..... the Daktarin has been working. She’s nearly back to her old self. Unfortunately when I reintroduced her the other smallest chick, a Legbar, went for her repeatedly so that one is now in chicken jail. She is happily clucking around withe the 2 copper Marans. Being gluttons for punishment we bought another Eglu comes complete with 4 more chicks who look very neglected. We’ve only picked them up today and I’ve had to scrub the Eglu ....was just filthy. I’m guessing they have mites. Also poop doesn’t look right. It’s more brown yuk than white lumps. We’ll keep them separate for a few weeks and worm them but what is best for mites.
