At 8 weeks I increase their protean Intake. I have never had a CX die except for in shipping or buying chicks from farm supply store. Then Butcher at 10 weeks. Been doing that for a long time now and thus far has never done me wrong.
Since there is no rooster one or two of the hens could be taking the place of the rooster. Hens will stop laying a d could start crowing as well. It is a good idea to get a rooster if you are able to. Could be why they stopped laying. Really it's hard to say why they stopped but I have seen this...
And it is a possibility it could be mericks ( not sure if I spelled that right) disease. You will want to separate them. And it is a very good possibility it's stress from shipping as well. If not drinking real good you may need to force liquid with a syringe
Just because the vent wast clogged dosent fully mean it wasn't pasty butt could of just been the beginning of it. And keep on medicated feed. Would only feed the eggs once a day though. In my experience of feed more it could give them the runs.
Most of the time it is dehydration. The water with electrolytes is good. Maybe try some water with some raw apple cider vinegar. 1 table spoon to a gallon. The manure on the butt is pasty but usually do to getting to hot. And keep up with mixing the feed with water to make a mash so it's easier...
Honestly I would get them on flock raiser or all flock poultry feed. I don't no why ducks and chickens kill their young but it happens a lot. Kudos to you for jumping in to save the poor little baby.
Sounds like a nice flock. I've been thinking about doing 4-H as well with chickens to start my 3 year old daughter in it and get her seasons before she's old enough to do it herself. Welcome to BYC
I don't use those kind of feeders but I've been told by a friend that dose they used meal worm treats. Put them on the lid cause they can't stay away from dried meal worms. Also I've been told that propping it open just a couple inches for a week will help cause they can see the food and wil try...
Honestly I don't have a covered area for my birds either. I just go in the run once a week and dig up a couple inches of dirt for them. They will scratch around and get plenty of dirt. A good thing though if you want a special place is a small kiddy pool filled will fine dirt and some food grade...
Hmm I have been doing some looking into this and can't seem to find much about it. She gets enough oyster shell and grits? Have you tried backstrap molasses or raw apple cider vinegar? And have you made sure there isn`t something she is getting into thats toxic? This is intrigued with this issue
