I want photos
I don't think it is on this one. There is only one bird doing it and they all get raw meat in addition to ranging and eating lots of bugs at this point. I would think so if more were doing it. I have watched her on the roosts at night. I finally moved her so she isn't roosting with the others.
Be careful using the sand with the "littles". They don't understand what is food and what isn't and they will eat a good deal of it.
Sand can cause gizzard damage as it can abrade the lining of the gizzard.
I have littles right now without a mamma. I just use
paper towel ONLY for the first week or so, layering a new layer of paper towel over when they are soiled. That gives them a chance to learn what the food is without all those shavings in there.
At about 1 wk (actually a little sooner than a week) I brought in
a hand-full of litter from the hen house (I use pine shavings and some peat moss was in there too) then a little clean pine shavings. Not much needed. The area I have the food and water I keep using the paper towel. It works very well and the brooder isn't overwhelmed with shavings in water and feed as much.
And...with the paper towel maybe no allergies?
Also brought in a plug of sod from the area the adult chickens range...and change it out after they use it up.
That way they get exposed to the environment to which they are going and can build immunities gradually before they go out...which will be soon.
