@Leahs Mom do you let your broodies out into electric netting area with her chicks? Do the chicks go thru it?
The chicks can go through it.
Here's the deal. The last time I let the mamma decide when to take them out. She was very conservative at first not taking them out of the kennel. But she did take them out while they were tiny. They did go through other fence openings and totally freak her out from time to time - or get stuck on the other side and she didn't realize it. That makes me very nervous.
Plus - you said that you have crows. Crows WILL catch and eat little chicks and very easily if they get separated from mom.
The next time I have a broody I am planning on being more protective and keeping them in an area that has overhead protection unless I'm out working in the area for WAY LONGER than I did the last times. Those young'uns are such an easy prey that I feel like I need to protect them more than I did.
