This morning and tonight I saw my Barred Rock Rooster mounting my laying Golden Laced Wyandotte Hen and hear or my questions about incubating the eggs 1. What would the chicks look like with BR Roo and GLW Hen? 2. How long after breeding will the eggs be fertile (ie. 2 weeks) 3. It is between 32 degrees and 40 degrees at night and first thing in morning, will this cause a problem with using them to hatch? 4. How long can I hold the eggs before placing them into the incubator for hatching? 5. And how should I hold them (ie. on the counter or in fridge etc...)?
