Beekissed- Question, since we're on the topic of worming.
I've been following your posts about how you manage your flock and am planning to incorporate many of your philosophies into my keeping/husbandry as I can. Culling being one of them.
I have eight chickens right now of varying ages, none over 1yr; I've three young roo's, four pullets and one laying. I've never 'wormed' them but I've not seen anything that makes me think they need it. I do see one occasionally yawn and shake its head, but it seems more of a natural thing, like shaking out the feathers. They all look really healthy, nice feathers, one came to me with sparse wing/shoulder feathers but within a couple of weeks came in nicely. Everyone seems happy, albeit a little cramped, but happy.
I have a pen that's about 10x10 that I confine them to at night; all I have to do is shut the door, they put themselves to bed. They have a hutch and a repurposed 4x4 compost bin raised on plywood that they ALL pile into at night, leaving the hutch empty. I've put fresh hay in the comp bin several times only to find it scattered about the pen in the morning. They've shoved it all out down to the old poop-hay. I use hay bc shavings are too messy to keep in the bedding area. They'd have shavings all over the yard. The hay, they pretty much leave in their bed.
Right now the pen sopping wet. Its been raining a lot. Not much I can do but wait till it dries.
During the day they have the run of the backyard, about 40x20ft that they've de-grassed (but there's new growth constantly from the seeds I throw down being covered by leaves). I give them a slosh of ACV in their water every day; I don't wash the waterers unless I absolutely have to (haven't yet). They're fed primarily grower feed and I give them a few handfulls of wild bird seed mixed with dry oatmeal. What should I start thinking about feeding them next as their full diet, after they're off the grower feed?
I don't give them medicine of any sort and I don't want to start. However, I will have to cull two of the roo's pretty soon. I only wanted one and I think 1:5 is a good ratio. I'm still deciding which two look tasty. For sure the one that came with bad feathering.
With the given situation, what are your thoughts about worming or preventing a worm problem? I understand that they probably already have some worms and that's natural and not to worry about. I don't want a problem breaking out. Right now the plan is for the remaining roo to produce some chicks to replace anyone that needs getting rid of and not buying new chicks. So, heartiness is important here. What would you suggest for that as well?
BTW- if anyone else has advice, that'd be fine too. Keep in mind though though that I'm not interested in medicating with unnatural chemical medications.
AND- Thanks in advance!!
The areas I've highlighted could be a problem with your setup. Damp runs and housing is a perfect setup for parasites, both internal and external, not to mention some bad molds and bacteria as opposed to healthy growth and culture of good bacteria. I'd get the damp hay out of your sleeping area, place a board across your opening so you can contain your pine bedding, or just do without and take a leaf rake and rake out each and every day when you do your chores. Only takes a few minutes. Do they have a roost? Roosting is important for many reasons, one of which is that sleeping on a roost is nice and dry. They don't absolutely need one but I try to follow the natural way of things and roosting seems natural to me.
If you can't cover your run, I'd suggest trying to get good drainage going by ditching or building up one end of the run to form a slope. If this is impossible, maybe using some gravel base and sand to top it...something to give your birds dryer footing/run.
There are many ways to encourage regrowth of grass and folks on here seem to have some great ideas. My brother was telling me the other day about these interlocking plastic grids that come in sheets that one can put together right on the ground, they are pretty indestructible...they allow the growth of grass up through the holes in the grid but do not allow scratching and beating down of the ground and vegetation. They would give your birds some dry footing while allowing your grass to grow. I don't know how much they cost.
When my chickens are about 3-4 mo. old start back to feeding my older flock(and the youngsters) their laying mash, particularly at this time of year. Any supplements I offer right now are primarily calcium...no other whole grains. They are ramping up for peak laying season and they need the optimal fuel for that and laying mash has it. I don't care for the pellets and such but everyone has their own preference. I wouldn't be feeding the wild bird seed and dry oatmeal as it isn't necessary and is just filler when they need to be filling up on a good laying ration.
I'm not the chicken expert, by any means at all and I wouldn't mislead anyone with that idea...I just do what I do and it works great. I understand that not everyone has the setup I have and must adapt their setup as they go along. I had to do the same..everyone does. Find what works for you and provides the healthiest environment for your chickens and it should be alright.
For now I'd concentrate on getting your birds into a dryer setup, give some high quality, fresh feed, try to get some green in your range area one way or another and cull aggressively for healthy appearance and performance.
Same rooster was picked up (and dropped) by likely the same hawk, all of his birds went nuts and his amazon parrot, who could see it all from the window, started screaming "Bad bird! Bad bird!"
