Hi all. Still new here, so I'll try to give you the short version of my trials so far. Babies are almost 4 weeks old. I have to live stock water tanks. 14 in one, and 13 in the other. Temp has been kept correct throughout and now maintaining a 70-75 at all times. Started them on non medicated food. 3 days old, pasty butt on four of them. Maybe 5. Bedding is wood shavings. Pens, waterers, and feeders cleaned twice daily. Pasty butt under control in about a week and a half, during which time I switched to a med feed.Then started noticing runny poops. No blood, just not firm like most others. After about the start of week two, maybe sooner, I notice one of them has scissor beak. But eats and drinks like a true champ. Until this last week, in which I notice some of the birds seem to be breathing a bit harder while roosting, than the others. I am now going to start a third pen, in worry that overcrowding is seeming to be apparent. They have started challenging each other (some, not all), and I figure this is somewhat natural.....or is it? They ALL likes plucking the baby fuzz off each other, but not to the point of injury..(although some liked voicing their opinion with vigor). So now I was told ny the hatchery to med their water with sulfur for 7 days. Its been 24 hours and still seeing some of the runny poops. And the labored breathing in some. And quite a bit of what I may think is non-happy chirping from that second pen mostly but not exclusive. Got a combination of sounds going on, but Im not fluent in chicken yet to fully decipher whats being conveyed at all times. The outside pen is almost complete, and looking awesome....but I wont put them out until I know everyone is up to par. If anyone has seen my prior posts, you can see I have SilverLace, Welsummers, Black Giants, Buff Bantams, and New Hamps. Just trying to give you any and all info, so I can get best suggestions.Im already nervous as heck to introduce them to the outside world, and dont thinknows the time for sure. I had planned to introduce them in a grassy area starting at an hour, then after a few days of that, increasing their contained outside frolicking.I SO want them to be in the sun, fresh air, and 70's temps. BUT WHATS WRONG WITH THEM? Im sad for them. I dont wanna over med, over clean, over stress them. Whats my best course of action next. If you have any additional q's....PLZ feel free to ask. Ive already wrote have a novel here, and this is the short version ....Well, I tried anyway. LOL. I dont know what to do. Look forward to hearing from those who understand and can help. Thanks so much in advance. Lisa .
