Oh, they'll find a way to poop in it.....looks good though, they shouldn't be able to toss the food out with their beaks. I've got something similar planned.
The exposure to bugs, greens, and a little bit of native soil will also help the medicated feed establish the chicks defense against coccidiosis. As others have said, make sure they have access to some sort of grit, sort of course playground sand works great if you don't want to buy chick grit.
The crop is and organ in the upper breast/lower neck area where the chicken grinds (chews) their food. Sometimes it can become blocked and the contents begin to ferment which is why it is also called "sour crop". There is a lot of info on this forum regarding this condition as well as worming...
coccidiosis would be strange in a bird that old, I would suspect crop bound or possibly respiratory infection. The latter would usually present with a discharge from the nostrils.
1x1 is a little small, 2x2 is about right. Maybe the roosts are too low? Generally chickens will roost as high as they can, and they prefer cover, so if the roosts are in the open, they may feel too exposed. Have any pics? that would help
EEr's are hard to sex, at 6 weeks all you can really do is compare to the comb of the other EE. Maybe you might start to see(or not see hopefully) some shinier tail feathers starting.
This happened to me recently with an Ameraucana that I was "sure" was a pullet, until I noticed "her" comb was...
Tootsie is right, the medication is amprolium which is NOT an antibiotic, but a thiamine blocker. It blocks the uptake of thiamine that the coccidiosis needs to survive. So as long as the chicks are exposed to soil containing cocci and are on medicated starter, they will develop their own...
I am in love with this idea. I absolutely hate buying stuff. Another way to keep the algae to a minimum might be to paint the bottle opaque white to block the UV. You could even use a strip of tape vertically before you paint to leave a "window" so you can monitor the water level.
My neighbor kids do the same thing to/for my hens. Worst thing that's come of it is a little diarhea (sp) from time to time. As long as they are not eating so many treats that they neglect eating their food, they should be fine.
This ordinance has recently been changed. One can now house 6 hens, still no roosters allowed, still no permit necessary, and still no coop restrictions (although you must have one). I don't know how to add/change the entry above, so I just thought I'd comment here. So if you live in Boise, go...
That's what happened in my coop recently. Salmon Faverolles roo was getting abused by Welsummer roo. blood on the walls and and feeder...or anything that the comb contacted. Check for scabs on combs.
