My chicks are now a week old and I saw where I should add some grit to their brooder in prep for some treats such as egg and kale etc. I added some to their feed and the read another article that said not to mix in the food give seperately. I would love your input since this is my first batch of babies. The other question is I rehab and release baby squirrels. I have an outdoor release cage for the squirrels that is about 10 X 10 and perfect for the chicks as they get older until they go my fathers house. My concern was having the chicks take field trips in the release cage could introduce coccidia to my baby squirrels in the spring when I get baby squirrels going again. A friend of mine that sutudied avian said that the cooccidia was different in mammals and poultry. Does anyone know the answer to this? It would be a wonderful set up for the chicks to go outdoors for little stints but I cannot risk either of them crossing harmful coccidia to either. Thanks so much for any input !!!! Having a ball with the chicks. One week old now. All doing wonderful.
