I have 3 blrw hatches and in the brooder. 1 zipping and 1 pipped. 1 nothing to report yet. And 1 that possible died after the 1st 3 got done bowling and a big chunk of she'll fell off the towards the smaller end. Wrapped it in moist warm paper towel. Put it back, but no signs of life. Will wait a bit and try and keep that membrane from drying. I probably waited too long to investigate but didn't want to hurt the others.
